O. Ishitani et al., PHOTOCATALYTIC REDUCTION OF CARBON-DIOXIDE TO METHANE AND ACETIC-ACIDBY AN AQUEOUS SUSPENSION OF METAL-DEPOSITED TIO2, Journal of photochemistry and photobiology. A, Chemistry, 72(3), 1993, pp. 269-271
Deposition of a metal on TiO2 considerably accelerated photocatalytic
reduction of carbon dioxide to methane and/or acetic acid, and product
distribution was dependent on the kind of metal on the surface of TiO
2.
