reaction mechanismSummary Catalytic hydrogenation of CO2 to methanol is an exciting avenue to curb the rising CO2 emissions and generate renewable energy or value‐added products. Methanol synthesis via the thermal catalysis route gets increasing emphasis due to its fast kinetics and flexible combination...
CO2hydrogenation to methanol (reaction (1)) is an exothermic reaction. It theoretically prefers low-temperature reaction condition. Because there is a kinetic limitation at low temperatures, the reaction has to be therefore operated at reasonably higher temperatures. However, at elevated temperatures, ...
This confirms the previous theoretical study that In2O3inhibits the reverse water gas shift, a competitive endothermic reaction for methanol synthesis from CO2hydrogenation. The mechanism for CO2hydrogenation to methanol over In2O3catalyst has been discussed. 展开 关键词:...
CO2 hydrogenation to methanol on tungsten-doped Cu/CeO2 catalysts The catalytic hydrogenation of CO 2 to methanol depends significantly on the structures of metal-oxide interfaces. We show that doping a high-valency metal... Y Yan,RJ Wong,Z Ma,... - 《Applied Catalysis B Environmental》 被...
(AuxCu/ZnO, x = 0.001, 0.005, 0.02 and 0.05) catalysts in typical reaction temperature range for CO2hydrogenation to methanol. Over all the investigated catalysts, CO was detected as the main byproduct at various reaction temperatures. Negligible amount of methane was detected at 275 ºC...
In the current perspective we use ZrO2-containing catalysts as a model system to elucidate the governing principles for designing high performance catalysts with multiple active components for CO2 hydrogenation to methanol. 展开 关键词: reaction mechanisms interaction synergy ZrO2-containing catalysts ...
