AB  - Ag<sub>3</sub>PO<sub>4</sub> exhibits a high photocatalytic activity if exposed to visible light, however, it displays bottlenecks such as poor cycle-stability and mediocre ability to degrade methyl orange (MO) because of limited adsorption of MO molecules onto its surface. In this study, nano TiO<sub>2</sub> prepared by a one-step method was combined with Ag<sub>3</sub>PO<sub>4</sub> to form a TiO<sub>2</sub>@Ag<sub>3</sub>PO<sub>4</sub> heterojunction in order to improve this material both in terms of photocatalysis and photostability. After adding a KH-570 silane coupling agent, the photocatalytic performance of TiO<sub>2</sub>@Ag<sub>3</sub>PO<sub>4</sub> could be improved even further, with the degradation rate of MO maintained at more than 90% after three cycles of visible in light.
