摘要：BiPO4/g-C3N4 with different amounts of BiPO4 was prepared through wet impregnation with calcination method. The BiPO4/g-C3N4 showed large surface area (172.9 m(2) g(-1)) and the incorporation of BiPO4 caused a red-shift of g-C3N4 in visible light. The photocatalytic degradation of toluene over the samples was investigated. The degradation of toluene could get 82% in BiPO4/g-C3N4 photocatalysts under optimum reaction conditions. The BiPO4/g-C3N4 exhibited a higher photocatalytic activity than pure g-C3N4 or BiPO4. The improved photoactivity of BiPO4/g-C3N4 could be attributed to strong absorption in visible light and effective separation of photoinduced hole-electron pairs between BiPO4 and g-C3N4.
