A novel spindle-shaped nanoporous anatase TiO2–Ag3PO4 heterostructure with high photocatalytic activity was successfully prepared by a simple method. The Ag3PO4 nanoparticles with a diameter of 20–50 nm were deposited on the surface of the spindle-shaped TiO2. The effect of Ag3PO4 nanoparticles amounts on the photocatalytic activity was investigated. The results showed that the TiO2–Ag3PO4 composite with the mass ratio of TiO2:Ag3PO4 = 1:2 displayed the highest photodegradation efficiency of methylene blue (MB) and Bisphenol A (BPA), which was more highly than that of Ag3PO4 nanoparticles and also indicated a high stability of photocatalytic degradation. The improved activity of the TiO2–Ag3PO4 composite could be attributed to the efficient separation of the photogenerated electron–hole pairs.
