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

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.
