Catalytic systems for hydrogenation of CO₂ to methanol

Carbon dioxide utilization is considered among priority tasks for sustainability. One of the hot topics is the process of CO₂ hydrogenation to produce methanol. Both thermocatalytic and electrocatalytic methods, as well as photocatalytic conversion have been proposed. In this review, we provide a survey of recent literature on thermocatalytic hydrogenation of CO₂ to methanol over heterogeneous catalysts. The main focus was made on the influence of the catalyst compositions, nature of the supports and process conditions on the selectivity and productivity of the process.
