Abstract The ternary heterostructured g‐C 3 N 4 /Ag/BiVO 4 photocatalyst was successfully fabricated by a facile in situ precipitation method. The as-prepared g‐C 3 N 4 /Ag/BiVO 4 heterostructures included g‐C 3 N 4 and Ag nanoparticles (NPs) assembling on the surface of leaf-like BiVO 4 nanostructures. The g‐C 3 N 4 /Ag/BiVO 4 composite exhibited higher photocatalytic activity than pure g-C 3 N 4 , BiVO 4 , Ag/BiVO 4 and g‐C 3 N 4 /BiVO 4 . The enhanced photocatalytic performance could be attributed to an efficient separation of electron–hole pairs through a ternary composite system, in which Ag nanoparticles acted as electron sinks. In addition, the quenching effects of different scavengers showed that the reactive O 2 •− and OH play the major role in the Rh B decolorization.
