The electrochemical CO2 reduction reaction towards value-added fuel and feedstocks often relies on metal-based catalysts. Organic molecular catalysts, which are more acutely tunable than metal catalysts, are still unable to catalyse CO2 to hydrocarbons under industrially relevant current densities for long...
This study evaluated the coupling reaction of CO2 with methane via trimetallic catalyst based on ZrO2/TiO2 to produce acetic acid. The catalysts were characterized by various techniques including XRD, BET for textural properties, NH3-TPD and H2-TPR. The surface acidity of trimetallic catalyst was ...
Designing highly efficient electrocatalysts for electrochemical reduction of CO2(ERC) to value-added chemicals is a better approach to balance carbon emission. In this paper, through density functional theory (DFT) calculation, we study the catalytic performance of the catalyst supported on nitrogen-dope...
Electrochemical conversion of CO2 into value-added chemicals holds promise to enable the transition to carbon neutrality. Enhancing selectivity for a specific hydrocarbon product is challenging, however, due to numerous possible reaction pathways of CO2 electroreduction. Here we present a Cu–polyamine hyb...
近日,电子科技大学董帆教授在国际顶级期刊Angewandte Chemie International Edition上发表题为“Crystal plane is not the key factor for CO2-to-methane electrosynthesis on reconstructed Cu2O microparticles”的研究工作。作者采用电化学原位拉曼和原位表面增强红外光谱(SEIRAS)技术,并结合DFT理论计算揭示了原位重构形成的...
an effective synergy between the active Ni sites and surface oxygen vacancies on In2O3 causes a superior catalytic performance for CO2 hydrogenation with high methanol selectivity.Carbon monoxide is the only by product detected.The formation of methane can be ignored.When the reaction temperature is...
Ce0.96Ru0.04O2 and Ce0.95Ru0.05O2 perform best, converting 55% of CO2 with a 99% selectivity for methane, at a temperature of 450 °C. This is comparable to the best catalysts found previously for this reaction. Ce0.95Ru0.05O2 was characterized by XRD, electron microscopy, BET, XPS, IR...
(1 atm) for 3 h, followed by exposure to TfOH. b) Yields were determined by1HNMR with CH2Br2as internal standard, and isolated yields were provided in parentheses. c) Reaction time of step 1 is 6 h. d) N2inste...
AGWA chemical reactions are really three-reactant transformations in the liquid phase with 1:1 amine to acid gas mol ratio. Water is necessary at high mol ratio to amine (8:1 or 7:1), otherwise the reaction simply does not evolve sufficiently, leaving non-solvated amine unconverted...
20,21,22,23]. For example, mixotrophically growing cultures ofMethanosarcina barkeriform their biomass equally from methanol and CO2; however, almost all the methane is formed from methanol rather than from CO2since methanol is disproportionated to methane and CO2according to the following reaction...
