Abstract

Ag3PO4 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 TiO2 prepared by a one-step method was combined with Ag3PO4 to form a TiO2@Ag3PO4 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 TiO2@Ag3PO4 could be improved even further, with the degradation rate of MO maintained at more than 90% after three cycles of visible in light.
