Remarkable solvent tunable aggregation caused quenching for fluorochromic chitosan based hydrogel

Fabrication of Hydrogel with solvent tunable fluorescence property has a novel and significant contribution in current research. Herein, chitosan, functionalized with Fluorescein mono-aldehyde, a light emitting molecule forms a smart strong polymeric gel having nanofibrous architect within micro molecular assembly. Multi functionalities, dynamic and reversible non covalent interactions associated with Fluorescent hydrogel have been portrayed in terms of change in photoluminescence with variation of pH, solvent and temperature in the sol phase. The hydrogel exhibits the distinct photoinduced electron transfer (PET) process within itself. Aggregation caused quenching (ACQ) phenomenon occurs in mixing the suitable pH solutions and Pyridine (similar to 20 fold quenching of fluorescence) and Tetrahydrofuran (similar to 325 fold quenching of fluorescence) with the gel solution. The mechanisms of PET and ACQ process have been well explained with quantitative fluorescence measurement and various kinds of host-guest interactions specially pi-pi interactions and H-bondings. Aggregation of solvent molecules with Fluorescent hydrogel networks has been established by dynamic Light scattering (DLS) study. This aggregation based photoluminescence phenomenon would acquire more response for the extensive usefulness in chemical, biological and material research in future. (C) 2020 Elsevier B.V.

High-performance composite H-ZSM-5/alumina catalyst for the methanol-to-ethylene conversion

A series of extruded H-ZSM-5/alumina composite catalysts were prepared and characterized using N-2 sorption isotherm, transmission electron microscopy, scanning electron microscopy, infrared spectroscopy, X-ray diffraction, NH3-TPD, and pyridine adsorption. The methanol conversion over the as-prepared catalyst as well as its components was studied at 500 degrees C. The catalysts with H-ZSM-5/alumina ratio 3/1 and 1/1 (by mass) catalyst exhibited the highest ethylene selectivity (up to 44%) and the ethylene/propylene ratio up to 10/1, whereas zeolite H-ZSM-5 demonstrated the propylene selectivity up to 30% and the ethylene/propylene ratio 1/8. In contrast, the catalyst with the H-ZSM-5/alumina ratio 1/3 demonstrated no activity toward olefins synthesis. The as-prepared H-ZSM-5/alumina catalysts have a long lifetime in the methanol-to-hydrocarbons conversion, which is several times higher compared to pure zeolite H-ZSM-5. The catalyst regeneration results in recovering the initial catalytic activity. The obtained findings reveal that embedding microporous zeolite in the mesoporous alumina matrix facilitates the mass transfer limitations and decreases the number of strong acid sites. These factors govern an essential performance of the as-prepared catalyst in the methanol-to-ethylene reaction.

Electrochemical Kinetic Study of [Cp*Rh] Complexes Supported by Bis(2-pyridyl)methane Ligands

Redox-induced reactions of organometallic complexes are ubiquitous in molecular electrochemistry and electrocatalysis research. However, a detailed knowledge of the kinetic parameters associated with individual elementary steps in these reactions is often challenging to obtain, limiting an understanding of the reactivity pathways that can be used to construct new catalytic cycles. Here, the kinetics of redox processes in model [Cp*Rh] complexes have been explored with substituted bis(2-pyridyl)methane (dipyridylmethane, dpma) ligands. Complementing prior work with [Cp*Rh] complexes bearing 2,2′-bipyridyl ligands, we find that the redox chemistry in these species is strongly affected by the disrupted inter-ring conjugation of dpma ligand frameworks. In particular, [Cp*Rh] complexes bearing kappa(-2)-dpma ligands with varying substitution at the bridging methylene position undergo a unique electrochemical-chemical (EC) process upon reduction from Rh(II) to Rh(I) as observed by cyclic voltammetry; transient electrogenerated Rh(I) species undergo a ligand rearrangement that results in facial eta(2) coordination of one pyridine motif on the dpma platform. Studies of a family of [Cp*Rh] complexes bearing dimethyl (Me(2)dpma)-, dibenzyl (Bn(2)dpma)-, methyl,methylpyrenyl- (MePyrdpma)-, and bis(methylpyrenyl) (Pyr(2)dpma)-substituted dpma ligands reveal a uniform trend in the first-order rate constants associated with this EC process involving ligand rearrangement, providing kinetic insight into a key process that enables the stabilization of low-valent rhodium by substituted dpma-type ligands.

Effect of alkali (Cs) doping on the surface chemistry and CO2 hydrogenation performance of CuO/CeO2 catalysts

The reaction of captured carbon dioxide with renewable hydrogen towards the eventual indirect production of liquid hydrocarbons via CO2 reduction to CO (reverse water-gas shift reaction, rWGS) is a promising pathway in the general scheme of worldwide CO2 valorization. Copper-ceria oxides have been largely employed as rWGS catalysts owing to their unique properties linked to copper-ceria interactions. Here, we report on the fine-tuning of CuO/CeO2 composites by means of alkali promotion. In particular, this work aims at exploring the effect of cesium doping (0-4 atoms Cs per nm(2)) on co-precipitated CuO/CeO2 catalysts under CO2 hydrogenation conditions. The as-prepared samples were characterized by N-2 physisorption, X-ray diffraction (XRD), H-2-temperature programmed reduction (H-2-TPR), X-ray photoelectron spectroscopy (XPS), CO2-temperature programmed desorption (CO2-TPD), Fourier-transform infrared spectroscopy (FTIR) of pyridine adsorption and CO-diffuse reflectance Fourier-transform infrared spectroscopy (CO-DRIFTS). The results demonstrated that a low amount of Cs exerted a beneficial effect on CO selectivity, inhibiting, however, CO2 conversion. Specifically, a doping of 2 atoms Cs per nm(2) offers > 96 % CO selectivity and equilibrium CO2 conversion at temperatures as low as 430 degrees C, whereas further increase in cesium loading had no additional impact. The present findings can be mainly interpreted on a basis of the alkali effect on the textural and acid/base properties; Cs doping results in a significant reduction of the surface area and thus to a lower population of active sites for CO2 conversion, whereas it enhances the formation of basic sites and the stabilization of partially reduced Cu+ species, favoring CO selectivity.

Effects of reaction conditions on one-step synthesis of methylal via methanol oxidation catalyzed by Mo:Fe(2)/HZSM-5 catalyst

In the process of one-step synthesis of methylal via methanol oxidation, the design and research of various dual-function catalysts are important and studies on the influence of reaction conditions on this type of process are scarce. We explored the influence of reaction temperature, reaction space velocity, and the feed ratio of methanol to air on the catalytic effect of the process based on the Fe-Mo-based bifunction catalyst and discovered the most appropriate reaction conditions for the process. Results showed that excessively high reaction temperatures were not conducive to the formation of target product Dimethoxymethane (DMM) and this was verified from the perspective of thermodynamic analysis. At the same time, through Brunaure Emmett Teller (BET), X-ray diffraction, scanning electron microscope, NH3-temperature-programmed chemisorption, and Pyridine Fourier Infrared (PY-FTIR) characterization, analysis of the microstructure and surface characteristics of the catalyst showed that an excessively high reaction temperature caused accumulation of metal oxides on the catalyst surface to block pores and reduce the specific surface area. This also destroyed the active acidic sites on the catalyst surface and weakened the acidity of the catalyst, thereby reducing catalytic activity. Investigation showed that excessively high reaction space velocity caused most of the formaldehyde obtained by catalyzing the initial oxidative dehydrogenation to fail to undergo polycondensation with methanol after desorption in time to obtain DMM, leading to a significant decrease in DMM selectivity. Investigation of the methanol-air feed ratio showed that when CH3OH:air = 1.5, the methylal selectivity was highest and catalytic activity had improved. Orthogonal experiments showed that optimal reaction conditions of the process were 663 K, 15 000 h(-1) and CH3OH: air = 0.82. In addition, compared with other bifunctional catalysts of this process, the self-made Mo:Fe(2)/HZSM-5 bifunctional catalyst exhibited high stability and carbon deposition resistance under severe operating conditions.

Incorporation-limiting mechanisms during nitrogenation of monolayer graphene films in nitrogen flowing afterglows

Monolayer graphene films are exposed to the flowing afterglow of a low-pressure microwave nitrogen plasma, characterized by the absence of ion irradiation and significant populations of N atoms and N-2(A) metastables. Hyperspectral Raman imaging of graphene domains reveals damage generation with a progressive rise of the D/G and D/2D band ratios following subsequent plasma treatments. Plasma-induced damage is mostly zero-dimensional and the graphene state remains in the pre-amorphous regime. Over the range of experimental conditions investigated, damage formation increases with the fluence of energy provided by heterogenous surface recombination of N atoms and deexcitation of N-2(A) metastable species. In such conditions, X-ray photoelectron spectroscopy reveals that the nitrogen incorporation (either as pyridine, pyrrole, or quaternary moieties) does not simply increase with the fluence of plasma-generated N atoms but is also linked to the damage generation. Based on these findings, a surface reaction model for monolayer graphene nitrogenation is proposed. It is shown that the nitrogen incorporation is first limited by the plasma-induced formation of defect sites at low damage and then by the adsorption of nitrogen atoms at high damage.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14338-32-0, in my other articles. Formula: C6H7ClIN.

Effects of amino acid ionic liquids with different cations ([N2Py], [N-2222], [P-2222], and [C(2)mim]) on wheat seedlings

The ecotoxicity of four ionic liquids with different cations (N-ethyl-pyridine alanine [N2Py][Ala], tetraethyl phosphine l-alpha-amino propionic acid salt [P-2222][Ala], 1-ethyl-3-methyl-imidazolium alanine [C(2)mim][Ala], and tetraethyl ammonium l-alpha-amino propionic acid salt [N-2222][Ala]) was assessed in hydroponically-grown wheat seedlings at concentrations from 200-1200 mg L-1. The results showed that type of cation has a significant influence on the growth, chlorophyll and nutrient uptake of wheat seedlings (P < 0.05). We observed decreased dry weight and shorter roots and shoots in the treated seedlings with increasing IL concentrations. The contents of Chl a and Chl b in wheat seedlings exposed to ILs showed the trend of firstly increasing followed by a decrease with increasing IL concentrations, but they peaked at different concentrations of ILs. In addition, the exposure of wheat seedling to ILs containing different cations (200-1200 mg L-1) led to first an increase and then a decrease of nitrogen content, and reduced the content of phosphorus and potassium. Moreover, the cellular structures, including nuclei, mitochondria, chloroplasts, cell membranes, and the cell walls of wheat leaf and root were affected to varying degrees by 600 mg L-1 ILs. The negative impacts of ILs on wheat seedlings ranked from high to low were: [N2Py][Ala] > [N-2222][Ala] > [P-2222][Ala] > [C(2)mim][Ala]. In this work, the relatively stronger toxicity of [N2Py][Ala] was likely contributed by ethanol, which was used to dissolve [N2Py][Ala]. Therefore, it is not recommended to use N-ethyl-pyridine alanine ([N2Py][Ala]) widely in practical applications.

Tin oxide nanostructure fabrication via sequential infiltration synthesis in block copolymer thin films

Tin oxide (SnO2) nanostructures are attractive for sensing, catalysis, and optoelectronic applications. Here we investigate the fabrication of SnOx nanostructures through sequential infiltration synthesis (SIS) in block copolymer (BCP) film templates. While the growth of metal and metal oxides within polymers and BCP films via SIS has been demonstrated until now using small precursors such as trimethyl aluminum and diethyl zinc, we hypothesize that SIS can be performed using larger precursors and demonstrate SnOx SIS with tetrakis(dimethylamino)tin (TDMASn) and hydrogen peroxide. Tuning the SIS reaction and BCP chemistry resulted in highly ordered, polystyrene-block-poly(2-vinyl pyridine) (P2VP)-templated porous SnOx – AlOx and SnOx nanostructures. Detailed investigation using in-situ microbalance, high resolution electron microscopy, elemental analysis and infra-red spectroscopy shows that SnOx can directly grow within P2VP homopolymer and BCP films. Simultaneously with the growth, SnOx SIS process also contributes to the polymer etch. Performing SnOx SIS with pretreatment of a single AlOx SIS cycle increases the SnOx growth and protects the BCP template from etching. This is the first report of SnOx SIS opening a pathway for additional tetrakis-based organometallic precursors to be utilized in growth processes within polymers. (C) 2019 Elsevier Inc.
