Isotopic transient kinetic analysis of CO2 hydrogenation to methanol on Cu/SiO2 promoted by Ga and Zn
Journal of Catalysis(2022)
摘要
•Cu/SiO2 catalysts promoted with Zn and Ga with similar Cu particle size.•SSITKA investigation for CO2 hydrogenation.•Zn and Ga increase the number of active sites for CO formation.•Parallel mechanism for CO formation operates on CuZn/SiO2 catalysts.•A low fraction of the surface is active for the reaction.
