To develop the photocatalyst with high activity and easy recyclability, uniformly loaded Cu3P NPs in N-doped porous carbon (NPC) supported by foamy copper (FC) was synthesized through a multi-step calcination method. FC was modified by in-situ growth of copper-based metal-organic framework (Cu-MOF) crystals, which was further calcinated to obtain Cu2O/Cu NPs loaded NPC on the surface of FC (Cu2O/Cu@NPC@FC-400). The desired photocatalyst Cu3P@NPC@FC-400 can be achieved after phosphate treatment. The composition and morphology of the obtained material were characterized by X-ray powder diffraction (PXRD), infrared spectroscopy (IR), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The photocatalytic performance of Cu3P@NPC@FC-400 was studied in the simulated dye wastewater of Rhodamine B (Rh B), and the degradation mechanism was explored as well. It is found that the catalyst exhibits good photocatalytic activity for Rh B with a high dye removal up to 94% within 3 h. The photocatalyst is convenient for recovery, and its activity remains after 10 runs. Moreover, Cu3P@NPC@FC-400 shows excellent photodegradation performance for multi-component wastewater containing 7 dyes. The photocatalyst has the advantage of good stability and easy recovery, which can be used for treating wastewater of various dyes.
