Asymmetric Sites on the ZnZrO x Catalyst for Promoting Formate Formation and Transformation in CO2 Hydrogenation

Zhendong Feng et al.

Summary: The role of formate species for CO2 hydrogenation was investigated on ZnZrO (x) catalyst. It was found that bidentate carbonate formed from CO2 adsorption is hydrogenated to formate on Zn-O-Zr sites. The asymmetric Zn-O-Zr sites promote both formate formation and transformation, leading to the excellent performance of the ZnZrO (x) catalyst for methanol formation.

Cu-Ga3+-doped wurtzite ZnO interface as driving force for enhanced methanol production in co-precipitated Cu/ZnO/Ga2O3 catalysts

Jorge Cored et al.

Summary: This study presents a detailed understanding of the interactions among the active components in gallium promoted Cu/ZnO catalysts, depending on the speciation of the gallium, and their effect in the CO2 hydrogenation to methanol. The promoting effect of Ga3+-doped in the wurtzite ZnO lattice is compared to that of a zinc gallate phase. It is found that the Ga3+-doped ZnO sample exhibits a strong inhibition of CO formation and an enhanced methanol formation, particularly under conditions where the reverse water gas shift reaction predominates. The catalytic performance is correlated with the microstructure of the catalyst, including a surface enrichment with reduced ZnOx species, stabilization of positive charged copper species, and an increase in the amount of surface basic sites for CO2 adsorption.

Wenlong Wu et al.

Summary: The hydrogenation of CO2 using renewable power-generated hydrogen is a promising way to achieve a sustainable carbon cycle. However, the role of water in CO2 hydrogenation is still debated. This study found that both too low and too high water contents hindered the synthesis of methanol over Cu/ZnO catalysts. The optimal water content was 0.11 vol. %, resulting in high methanol selectivity and CO2 conversion.

The role of Cu1-O3 species in single-atom Cu/ZrO2 catalyst for CO2 hydrogenation

Huibo Zhao et al.

Summary: This study reports a novel copper-based catalyst with isolated active copper sites for the hydrogenation of CO2 to methanol. The Cu-1-O-3 units in the Cu-Zr catalyst are found to contribute solely to methanol synthesis, while small copper clusters or nanoparticles with Cu-Cu structural patterns are responsible for the formation of CO by-product. Additionally, the migration of Cu-1-O-3 units to the catalyst surface during the catalytic process accelerates CO2 hydrogenation. These findings extend the application potential of single-atom catalysts for thermal catalytic CO2 hydrogenation and provide insights for the design of high-performance copper-based catalysts to meet industrial demand.
