The pursuit of cleanliness, energy efficiency, and resource preservation through photochemical reactions has led to the emergence of novel pathways and methodologies in synthetic chemistry, rendering it one of the most dynamic research domains within modern organic synthesis. Carbon dioxide (CO₂), owing to its non-toxic, cost-effective, abundant, and recyclable attributes, serves as an optimal C1 precursor in synthetic chemistry. Recent years have witnessed rapid advancements in the photochemical conversion of CO₂ into carboxylic acid compounds, offering a gentle and highly efficient synthetic approach for their production. An overview of the research progress on the synthesis methodologies of carboxylic acid compounds through photochemical CO₂ conversion is provided, while certain associated reaction mechanisms are also elucidated.

Key words: carbon dioxide, photocatalysis, carboxylation
