ROLE OF BISMUTH VANADATE AS A PHOTOCATALYST FOR THE REDUCTION OF MALONIC ACID

The photocatalytic reduction of malonic acid was carried out in presence of bismuth vanadate and visible light. The effect of various parameters like pH, concentration of malonic acid, amount of bismuth vanadate and light intensity has been studied. A tentative mechanism has been proposed for photocatalytic reduction of malonic acid involving bismuth vanadate as a photoreductant. The product was characterized as a mixture of aldehyde and alcohol.
