Isotopic transient kinetic analysis of CO2 hydrogenation to methanol on Cu/SiO2 promoted by Ga and Zn

Daviel Gomez et al.

Summary: In this study, the effect of promoters such as Zn and Ga on the number and intrinsic activity of surface sites in Cu-based catalysts was assessed using steady state isotopic transient kinetic analysis. The results showed that the addition of Zn and Ga significantly increased the concentration of surface intermediates leading to CO, while reducing the intrinsic rate of CO formation. This led to a comparable macroscopic CO formation rate compared to non-promoted Cu. The quantification of surface intermediates confirmed the unique configuration of active sites for this reaction.

Improving robustness of kinetic models for steam reforming based on artificial neural networks and ab initio calculations

Natalia Morlanes et al.

Summary: In this study, a methodology based on artificial neural networks was developed to improve the kinetic model for steam reforming. By analyzing different strategies and adsorption mechanisms, the most suitable kinetic model was obtained. The versatility of the proposed model and the strengths and weaknesses of the data-driven approach for selecting the kinetic model were proven through validation experiments with different conditions and feeds.

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.

Experimental and theoretical studies of CO2 hydrogenation to methanol on Ru/In2O3

Qinglei Wu et al.

Summary: In this study, a Ru/In2O3 catalyst with high dispersion and activity was prepared by deposition precipitation method for CO2 hydrogenation to methanol. The Ru loading enhanced the activation ability of hydrogen and CO2, leading to high methanol selectivity and space-time yield. Theoretical analysis showed that the CO-hydrogenation route on Ru/In2O3 was thermodynamically favored for methanol production from CO2.

Chenyang Shen et al.

Summary: Iridium (Ir) catalysts supported by indium oxide show high activity and selectivity in CO2 hydrogenation to methanol, with higher Ir loading leading to enhanced activity. The intense interaction between Ir and In2O3 on the catalysts results in high dispersion and the Ir-In2O3 interface as the active site for selective hydrogenation of CO2 into methanol.

Ni-In Synergy in CO2 Hydrogenation to Methanol

Jiadong Zhu et al.

Summary: This study investigates the promotion of Ni on In2O3 and optimization of NiO-In2O3 catalyst for CO2 hydrogenation. Ni facilitates the synthesis of CH3OH by reducing the dissociation barrier of H2, leading to reduced activation energy for CO2 hydrogenation. The interaction between Ni cations and In2O3 at low NiO loading enhances the surface density of oxygen vacancy, promoting the hydrogenation of adsorbed CO2 on O-v.

Combined experimental and computational study to unravel the factors of the Cu/TiO2 catalyst for CO2 hydrogenation to methanol

Sachin Kumar Sharma et al.

Summary: The study investigated the hydrogenation of CO2 to methanol over Cu nanoparticles supported on TiO2 nanocrystals at high pressure and temperature. It was found that the Cu-TiO2HT catalyst exhibited superior catalytic activity and methanol selectivity compared to Cu-TiO2IMP catalyst due to the formation of smaller Cu nanoparticles. Density functional theory calculations indicated a lower CO2 activation barrier on Cu nanoparticles, contributing to the higher selectivity towards methanol. Time of stream studies showed no significant deactivation of Cu-TiO2 catalysts even after 150 hours of operation.
