The properties of the In2O3-ZrO2, In2O3-Ga2O3-ZrO2 and In2O3-Co3O4-ZrO2 catalysts for the reaction of CO2 hydrogenation to methanol were studied. It has been determined that with an increase in indium oxide content, the catalytic activity passes through its maximum at In2O3 content 10 wt%. It is shown that the introduction of cobalt oxide into the catalyst increases the selectivity for methanol and increases CO2 conversion. This is due to an increase in the number of oxygen vacancies on the surface of the catalyst. Promotion with gallium oxide, on the contrary, leads to a decrease in activity in the methanol synthesis reaction. Among the series of catalysts studied, In2O3-Co3O4-ZrO2 exhibits the greatest activity, which achieves 11.1 % CO2 conversion with 71 % selectivity to methanol at a pressure of 40 atm and 300 °C. It is also shown that this catalyst operates without a loss of activity for 30 h under these conditions.
