In the context of achieving carbon neutrality, CO2 catalytic conversion technologies are effective in reducing atmospheric CO2 concentrations while simultaneously producing renewable products. This approach is seen as a viable method for constructing a new carbon cycle, thereby effectively addressing the issue of global warming. Photothermal CO2 conversion has recently emerged as a promising research focus due to its high energy utilization efficiency, superior CO2 conversion, excellent product selectivity, mild operating conditions, low energy consumption and minimal operating costs. Cerium oxide (CeO2) has been widely used in photothermal catalysis due to its unique chemical properties, particularly when used as a support material with supported metals, creating distinctive interfacial sites for catalytic reactions. As an emerging star support in photothermal CO2 conversion, its contributions are equally significant and should not be overlooked. However, to our knowledge, there has been no comprehensive review of CeO2 applications in catalytic hydrogenation of CO2. In this paper, we summarize and discuss CeO2-based materials for photothermal CO2 conversion to value-added products. This research particularly focuses on the synthesis methods of CeO2-supported catalysts, the history of CeO2 in photothermal catalysis, types of photothermal catalytic reactors, unique characterization methods for the photothermal catalysts and the photothermal CO2 hydrogenation reactions by CeO2-...
