摘    要:Heterogenous photocatalyzed reduction of aqueous Na2CO3 has been carried out by using nano SrFeO3 semiconductor powders.Formic acid,formaldehyde and methyl alcohol were identified as photoproducts,and were measured spectrophotometrically.The effect of the variation of different parameters such as sodium carbonate concentration,amount of photocatalyst and different light sources on the yield of photoproducts was also investigated.It shows that nano SrFeO3 has photocatalytic activity.Irradiation leads to the production of electrons in the conduction band of the SrFeO3 semiconductor.It is likely that the photoproduced electrons reduce CO3^2- initially to HCOO^-,and then to HCHO and CH3OH.

Abstract:Heterogenous photocatalyzed reduction of aqueous Na2CO3 has been carried out by using nano SrFeO3 semiconductor powders. Formic acid, formaldehyde and methyl alcohol were identified as photoproducts, and were measured spectrophotometrically. The effect of the variation of different parameters such as sodium carbonate concentration, amount of photocatalyst and different light sources on the yield of photoproducts was also investigated. It shows that nano SrFeO3 has photocatalytic activity. Irradiation leads to the production of electrons in the conduction band of the SrFeO3 semiconductor. It is likely that the photoproduced electrons reduce CO32- initially to HCOO-, and then to HCHO and CH3OH.
