摘要
The photoreduction of aqueous sodium and potassium carbonates has been performed in the presence of a malachite green (MG) solution (which is a photocatalyst also). The photocatalytic formation of formic acid and formaldehyde were measured spectrophotometrically using Nash reagent. The effects of variations of various parameters, like pH, amount of photocatalyst (MG concentration), concentration of Na2CO3 and K2CO3, light intensity etc., on the yield of photoproducts were also investigated. A tentative mechanism for this reduction has been proposed. (C) 2003 Elsevier Ltd. All rights reserved.
