Title: Photocatalytic reduction of carbon dioxide on p-type CaFe[sub 2]O[sub 4] powder

Abstract

The photocatalytic reduction of CO[sub 2] on p-type CaFe[sub 2]O[sub 4] powder has been studied in water. CH[sub 3]OH and HCHO were produced under illumination. The additions of NaH[sub 2]PO[sub 2] and BaCO[sub 3] promoted the CO[sub 2] reduction reaction on the CaFe[sub 2]O[sub 4] photocatalyst. It was proven from the dependence of the amount of CH[sub 3]OH produced on the wavelength of the illuminated light that the electron produced in the conduction band of the CaFe[sub 2]O[sub 4] reduces CO[sub 2]. The mechanism for the photocatalytic reduction of CO[sub 2] on CaFe[sub 2]O[sub 4] is briefly discussed. 10 refs., 4 figs.
