Abstract Photocatalytic reduction of carbon dioxide in aqueous media has been carried out over potassium‐ferrocyanide‐coated titanium dioxide powder. Formic acid and formaldehyde were identified as photoproducts, and were measured spectrophotometrically using Nash reagent. The effect of the variation of different parameters such as potassium ferrocyanide concentration, amount of photocatalyst (potassium‐ferrocyanide‐coated titanium dioxide powder), light intensity and particle size on the yield of photoproducts was also investigated. A tentative mechanism for this reduction has been proposed. © 1997 John Wiley & Sons, Ltd.
