Abstract: CO2 hydrogenation to methanol over Cu-ZnO-Al2O3 catalysts shows potential for CO2 emission reduction. The modification of the porous structure of the catalysts benefits the catalytic activity. Herein, the porous Cu-ZnO-Al2O3 catalysts were prepared via precipitation method with polymethylmethacrylate (PMMA) balls as templates. The results show that the average pore size and surface areas of Cu-ZnO-Al2O3 can be improved by PMMA templates without changing the crystalline structure. Lower PMMA ball usage and pore size favor the activity at low reaction temperatures, while higher PMMA usage and pore size benefit activity at high reaction temperatures. High calcination temperature can remove the residual carbon in the catalyst to improve catalytic activity. The modification of the porous structure of Cu-ZnO-Al2O3 catalysts can enhance the activity of CO2 hydrotreating to methanol.
