A series of ZnO/Fe 2 O 3 /g-C 3 N 4 photocatalysts were synthetized by impregnation of g-C 3 N 4 with Zn(NO 3 ) 2 ·6H 2 O, and Fe(NO 3 ) 2 ·9H 2 O followed by calcination. The morphology, chemical composition, and structure of the resulted materials were carefully analyzed by various characterization techniques. The photocatalytic performance of ZnO/Fe 2 O 3 /g-C 3 N 4 composites was evaluated based on the H 2 evolution from water splitting reaction. The results showed that the ZnO/Fe 2 O 3 /g-C 3 N 4 composite can effectively produce more H 2 than pure g-C 3 N 4 when irradiated under visible-light. H 2 production rate over 3-ZnO/Fe 2 O 3 /g-C 3 N 4 composite was of 25 μmol·h −1 , which is 4 times higher than that obtained in the presence of pure g-C 3 N 4 , clearly showing a significant improvement of the photocatalytic activity of the prepared nanocomposite. This result was attributed to the formation of a heterojunction between g-C 3 N 4 and ZnO/Fe 2 O 3 , which delayed the recombination of holes-electrons pairs and resulted in a remarkable increase in photocatalytic performance.

Semiconductor photocatalysts have broad prospects in the removal of antibiotics in water. In numerous semiconductor light catalyst materials, g‐C3N4 has attracted much attention because of its suitable band gap, high thermal and chemical stability. But its conductivity is poor, and the visible light utilization rate is low, which restrict the range of application. Modification strategies such as doping and semiconductor materials compounding can expand the visible light absorption range and maintain the advantages of high redox capacity of the photocatalyst. This article introduces the hazards of antibiotics in water, describes the progress of research on the modification of g‐C3N4 by metal elements, non‐metal elements, metal oxides and metal sulfides to remove antibiotics (TCs, SAs etc.) in water. Finally, we try to put forward some new research directions on the basis of the current research of photocatalyst, and put forward some simple views on the application of g‐C3N4.
