Abstract: The catalytic conversion of CO₂ to valuable chemical materials such as methane, methanol, carbon monoxide, methanoic acid, light olefins, arene, and so on is an important way for the carbon peak and carbon neutrality. Catalyst is one of the decisive factors in the conversion process, so the development of new catalysts with high conversion rate and selectivity is still the focus of CO₂ catalytic conversion research. The catalysts currently used are mainly noble metal catalysts, with some parts being transition metal catalysts. Moreover, some nonmetal catalysts, new catalysts and bulk catalysts are also proven to have good catalytic performance. With the complexity and heterogeneity of converted products increasing, the conversion rate and selectivity of CO₂ catalytic conversion turns lower. The catalytic reaction mainly contains thermocatalytic and photocatalytic, and the differences of catalytic conditions lead to the poor comparability of the performance of different kinds of catalysts. As a result, establishing standardized evaluation methods for CO₂ catalytic conversion will also be the key research area besides developing high-performance catalysts.
