Carbon dioxide is one of the most important greenhouse gases that cause global climate change. Reducing carbon dioxide emissions and converting it to chemicals and fuels with high-value are of great significance for sustainable development.Carbon dioxide hydrogenation to methanol utilizing green hydrogen produced from renewable resources such as solar energy is one of the important ways to solve the greenhouse effect and develop green energy. In recent years, non-copper-based catalysts represented by solid solutions have developed rapidly, showing good industrial application prospects. This paper reviews the research progress of non-copper-based catalysts for selective hydrogenation of carbon dioxide to methanol, with focuses on supported metal catalysts, bimetallic catalysts, solid solution catalysts, and indium oxide-based catalysts, so as to provide references for the design of efficient and stable methanol synthesis catalysts.
