In order to improve the photocatalytic degradation performance of Ag3PO4 and reduce the cost of photocatalyst made of Ag3PO4, a kind of Ag3PO4/TiO2 composite was successfully fabricated via a simply precipitation method for the Ag3PO4 nanoparticles being loaded on the surface of commercial titanium dioxide (P25) to form a heterostructure. The Ag3PO4/TiO2 composite were characterized by FT-IR, XRD, XPS, FE-SEM, HR-TEM, DRS and PL and applied for the degradation of formaldehyde solution under solar radiation. The results showed that the degradation rat of Ag3PO4/TiO2 composite (0.01796min(-1)) was much higher than that of pure Ag3PO4 (0.00775min(-1)), indicating that the Ag3PO4/TiO2 composite possessed better photocatalytic degradation activity for the formaldehyde solution than pure Ag3PO4. The composite significantly decreased the dosage of silver for photocatalyst under solar radiation, thereby reduced the cost of the photocatalyst made from silver. [GRAPHICS] .
