The Z-scheme BiVO 4 /α-Fe 2 O 3 photocatalyst was synthesized by a simple hydrothermal method. The photocatalyst is composed of α-Fe 2 O 3 nanocubes with a regular cubic structure and the BiVO 4 particles distributed on the surface of the α-Fe 2 O 3 nanocubes. The photocatalytic performance of Z-scheme BiVO 4 /α-Fe 2 O 3 photocatalyst was investigated in terms of its capacity for photodegradation of tetracycline hydrochloride. Improved photocatalytic activity was observed for Z-scheme BiVO 4 /α-Fe 2 O 3 photocatalyst compared with pure BiVO 4 and α-Fe 2 O 3 nanocubes under visible light irradiation. Studies of its morphology, physicochemical properties and photoelectrochemical behaviors demonstrated that BiVO 4 loading on the surface of α-Fe 2 O 3 nanocubes forms a Z-scheme heterojunction, which increases the specific surface area and significantly promotes the separation of photoinduced carriers. The main active species were determined to be OH and h + by ESR technique and trapping experiments. We propose a possible photocatalytic mechanism of Z-scheme BiVO 4 /α-Fe 2 O 3 photocatalyst system. This study may also provide a novel and eco-friendly demonstration of a useful strategy for the design and preparation of special structure photocatalytic materials.
