Effect of Ni content on Cu–Mn/ZrO₂ catalysts for methanol synthesis from CO₂ hydrogenation

Abstract

Cu–Mn/ZrO2 catalysts with different Ni contents were used for CO2 hydrogenation to methanol, among which the CMNZ-0.01 catalyst was the most effective, and the addition of Ni made the catalyst more oriented toward the COOH* pathway.

A systematic theoretical study of CO2 hydrogenation towards methanol on Cu-based bimetallic catalysts: role of the CHO&CH3OH descriptor in thermodynamic analysis

“…Herein, the bimetallic alloy model was constructed by substituting the copper atoms with other transition metal (TM) atoms (Au, Ni, Pd, Pt and Zn). The primary rationale for selecting TM atoms was based on a literature review, which identified Au–Cu, 4,36,37 Ni–Cu, 6,38,39 Pd–Cu, 7,40–42 Pt–Cu 43,44 and Zn–Cu 45–47 as extensively documented copper-based catalytic models. Choosing these models may help ensure that the combination of transition metals represented by Au, Ni, Pd, Pt and Zn demonstrates reliable catalytic activity when paired with copper.…”
