Experimental and theoretical study unveiling the role of solvents on CO activation and hydrogenation to methanol in three-phase reactor system

Vaibhav Pandey et al.

Summary: Syngas conversion to methanol in the slurry reactor requires selecting the suitable solvent. The activity test was conducted in a stirred tank slurry reactor with three different solvents (paraffin, diglyme, and DMSO) and CuZnO catalyst. Diglyme showed higher CO conversion and methanol selectivity compared to paraffin and DMSO. The role of solvents in CO adsorption on Cu(111) was studied by DFT combined with the COSMO model.

Investigating the role of oxygen vacancies and basic site density in tuning methanol selectivity over Cu/CeO2 catalyst during CO2 hydrogenation

Rajan Singh et al.

Summary: The study focuses on CeO2, ZrO2 and ZnO supported Cu catalysts, with Cu/ZnO showing the highest CO2 conversion rate and Cu/CeO2 demonstrating over 90% methanol selectivity at lower temperatures. The high methanol selectivity of Cu/CeO2 catalyst may be attributed to its excess surface oxygen vacancies and higher basic site density.

Design of highly stable MgO promoted Cu/ZnO catalyst for clean methanol production through selective hydrogenation of CO2

Sachin Kumar Sharma et al.

Summary: The synergistic interaction between small Cu particles and MgO/ZnO-supported catalysts synthesized by the hydrothermal method results in a high methanol production rate. The high activity of the catalyst may be attributed to the high Cu dispersion and large Cu surface area. The MgO support plays a promoting role in CO2 adsorption, leading to a preference for the selective CO2 hydrogenation pathway.
