Carbon dioxide (CO2) exerts a significant influence on climate change as a potent greenhouse gas. From a chemical standpoint, CO2 serves as an abundant and cost-effective “carbon one (C1)” resource with non-toxicity, renewability, and easy obtainability. The utilization of CO2 for synthesizing high-value-added chemicals represents an important avenue for addressing national strategic requirements and aligning with China’s objectives of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060. Organic photocatalysis can harness light energy to induce electron transfer in organic chemical reactions, facilitating bond cleavage and recombination processes. This approach offers advantages such as mild reaction conditions, environmental friendliness and exceptional selectivity. By integrating CO2 resource utilization with organic photocatalysis, novel opportunities arise for enriching carboxylation reactions. Two distinct types of photocatalytic carboxylation reactions, those involving carbon anions as pivotal intermediates and those featuring CO2 radical anions as key intermediates, are systematically elucidated.

Key words: photocatalysis, carbon dioxide (CO2), carboxylation, carbanion, carbon dioxide radical anion
