The photocatalytic formation of formic acid and formaldehyde from carbon dioxide in aqueous media has been carried out in the presence of neutral red coated titanium dioxide powder. These photocatalytic products were measured spectrophotometrically using Nash reagent. The effect of the variation of different parameters like neutral red concentration, the amount of the photocatalyst (Neutral red coated titanium dioxide powder), light intensity, particle size etc., on the yield of photoproducts was also investigated. A tentative mechanism for this reduction has been proposed.
