Enhanced Photocatalytic Activity of BiPO₄ Photocatalyst by Surface Modification of Fe(III) Cocatalyst

Abstract

Metal ions like Fe(III) were testified to be efficient co-photocatalyst in the field of environmental governance. Hence, a series of BiPO₄/Fe(III) materials were prepared via a hydrothermal method and impregnation. The experimental results indicated that normal organic dye was effectively removed by BiPO₄ with the presence of Fe(III) as a co-photocatalyst. The enhanced removal mechanism was attributed to the easy transfer of photo-induced electron-hole pairs and relatively high productivity of active redical by synergism of Fe(III).
