Abstract:

The catalytic hydrogenation of carbon dioxide (CO2) to chemicals, such as methanol, is a promising carbon capture, utilization and storage (CCUS) technology. The key challenge of CO2 hydrogenation is the development of efficient catalyst. Compared with traditional copper based catalysts, indium based catalysts have attracted much attention due to their high methanol selectivity and excellent high-temperature stability. And thus, In based catalysts have been paid more attention in recent years since they show high methanol selectivity and good stability at high temperature. However, the understanding of the mechanism and nature of In based catalysts for CO2 hydrogenation has not yet formed a unified theory. This review summarizes the research progress of catalyst from preparation methods, reaction mechanism, thermodynamic analysis and structure characterization. In view of the existing problems such as low single-pass conversion and insufficient catalyst stability, future research directions are proposed, including introducing extra promoters or active components, designing catalysts with special structures and coupling molecular sieves.

Key words: carbon dioxide, hydrogenation, methanol, catalyst, indium
