Visible-light Induced Photocatalytic Fixation of CO2 into Benzophenone Using Poly(p-phenylene) as a Photocatalyst

Article abstract of DOI:10.1246/cl.1993.983

Photoreductive fixation of CO2 into benzophenone can be achieved in a CO2-saturated DMF solution by using poly(p-phenylene) as a heterogeneous photocatalyst and triethylamine as an electron donor.The presence of quaternary ammonium salts increases the yield of benzylic acid as a CO2-photofixed product from benzophenone.
