Herein, it is the first time to report the catalytic role of H2O in the degradation of CH3NH3PbI3 perovskite by air of high humidity. It was found that H2O can catalyze the decomposition of CH3NH3PbI3 into CH3NH3I and PbI2, and then the crystal-to-amorphous phase transformation of the ...
Recently, however, an arene-anchored, electron-rich uranium complex has been shown to facilitate the electrocatalytic formation of Hfrom HO. Here, we present the precise role of uranium-arene 未 bonding in intermediates of the catalytic cycle, as well as details of the atypical two-electron ...
H2O and CO are artificially added during gas-oil catalytic hydrotreatment to investigate their influence in the potential biomass (i.e. lipids, bio-oil, tallow oil) catalytic co-hydroprocessing with fossil-based fractions for the production of hybrid fuels. Based on the experimental results, it ...
The symmetry of oxygen vacancy regulates the effect of H2O on toluene oxidation.The asymmetric oxygen vacancies accelerate H2O activation to generate OH species.The symmetric oxygen vacancies fail to activate H2O and cause competitive adsorption.MnO2-AsOv possesses high activity and stability for humid ...
Anthocyanins are ubiquitous plant pigments used in a variety of technological applications. Yet, after over a century of research, the penultimate biosynthetic step to anthocyanidins attributed to the action of leucoanthocyanidin dioxygenase has never be
Interestingly, many of the enzymes participating in these pathways generate specific ROS or RNS as byproducts of their normal catalytic function (Table 1) [31]. In this section, we will focus on the different types of ROS/RNS that can be generated inside peroxisomes. Table 1. Human ...
摘要: Potassium permanganate–copper sulphate in dichloromethane in the presence of a catalytic amount of water effects a smooth oxidative cyclization of ω-hydroxy alkenes to ω-lactones in good yields with the net loss of one or more carbon atoms in the process....
A new catalytic oxidation of CO involving an ionic process in the presence of H2O is proposed on a Pt-catalyst with specific promoting materials (co-catalysts). Oxidation of CO is very slow at room temperature on ordinary Pt-catalysts such as Pt/SiO2, Pt/Al2O3, Pt/TiO2, Pt/Graphite, ...
InOOH-OVfrom being further reduced during CO2conversion and increase the adsorption competitiveness for 5-hydroxymethylfurfural over hydroxide ions in alkaline electrolytes, making InOOH-OVa main-group p-block metal oxide electrocatalyst with bifunctional activities. Based on the catalytic performance of In...
hydrogen purification and production processes (preferential oxidation of CO, water鈥揼as shift reactions, and the reforming of bio-alcohols) is analyzed with an emphasis on the description of the physico-chemical properties of the interface that have a critical influence on the catalytic properties....
