摘要

CO2 emissions are key contributors to global climate change, leading to temperature increases and sea-level rise. Converting CO2 into valuable products is beneficial for meeting ‘Carbon Peaking’ and ‘Carbon Neutrality’ goals. Photocatalytic reduction of CO2 to produce liquid fuels is of great significance for both CO2 reduction and storage/transportation of high-value chemicals. However, so far, there is no relevant literature to summarize photocatalysts for CO2 conversion to obtain liquid products. Based on the thermodynamic examination of the catalytic process and basic principles guiding the design of the photocatalysts, this review summarized photocatalysts for the CO2 conversion into four liquid products: formic acid, methanol, acetic acid and ethanol. Based on this, strategic development goals are outlined, and innovative strategies are proposed to enhance the efficiency and product selectivity of photocatalysts in converting CO2 into liquid products. This review will serve as a valuable reference for CO2 photo conversion into liquid products.
