【 摘 要 】

As a common photocatalytic material, Ag3PO4 still faces the challenge including the fast recombination of photo-generated electron-hole (e--h+) pairs. In this work, we prepared Co3O4/Ag3PO4 heterojunction with good optical properties by an in-situ precipitation method. Compared to pure Ag3PO4, the Co3O4/Ag3PO4 exhibited greatly improved photocatalytic activities for degradation methylene blue (MB) and bisphenol A (BPA) under the visible light irradiation. Here, the degradation rate of MB could reach up to 12% which is about 35% higher than that of pure Ag3PO4, after 18 min irradiation. The degradation rate of BPA could reach up to 33% which is about 45% higher than the pure Ag3PO4. This work may provide insight for finding a new Ag3PO4 photocatalyst for promoting the photocatalytic performance.
