In this study, AgPO@NiS core/shell nanorod arrays on Ni foam substrate were fabrciated by a method of combining hydrothermal and in situ deposition. The resultant products were characterized by XRD, SEM, UV-vis, XPS and photocurrent response, respectively. The photocatalytic activity of AgPO@NiS were conducted by photodegradation rhodamine B (RhB) under visible light. The final results confirmed that the photocatalytic activity of AgPO@NiS samples show an obvious improvement compared with pure AgPO. This enhanced performance could be attributed to the fact the charge recombination can be effectively suppressed and the photocorrosion effect of AgPO can be inhibited as the photogenerated electrons on the conduction band of AgPO can inject to NiS. The maximum value of total removal rate were showed in AgPO@NiS-40 (where 40 represnsents the mass fraction of AgPO), which were 2.12 times than pure AgPO. More importantly, the AgPO@NiS-40 sample exhibits excellent stability under cyclic experiment. A plausible mechanism of photodegradation RhB over AgPO@NiS sample was also discussed.
