This work is devoted to the first demonstration of the synthesis of trichloroacetic acid from chloroform and CO2 in an aqueous solution over TiO2 under irradiation with UV light. The yield of trichloroacetic acid under chosen conditions exceeds 90% with the selectivity to the target product close to 100%. The mechanisms of trichloroacetic acid formation from chloroform and CO2 are considered.
