g-C 3 N 5 has wide-ranging applications in photocatalysis owing to its twodimensional layered structure, large surface area, and small band gap. In this study, the surface of g-C 3 N 5 was subjected to inorganic acid modification and combined with BiOCl to form a heterojunction, effectively improving the photocatalytic activity of the material. The rates of degradation of rhodamine B and ciprofloxacin by the 15-C 3 N 5 -BiOCl composite photocatalyst were 22.2 and 20.7 times higher, respectively, than those of degradation by g-C 3 N 5 . This was attributed to the Z-type heterojunction formed by g-C 3 N 5 and BiOCl, which significantly improved the efficiency of photogenerated electron-hole pairs separation and broadened the optical response range. The preparation of novel photocatalysts has broad application prospects in the treatment of organic pollutants in water.

The g-C3N5 has been widely used in the field of environmental remediation because of its narrow band gap energy and good visible light absorption. It is an excellent semiconductor photocatalytic material, but the recombination of photogenerated carriers greatly limits the photocatalytic performance of g-C3N5. Construction of heterojunctions is an efficient method to regulate the band gap structure, which can achieve efficient separation of photogenerated carriers and improve photocatalytic performance. In this study, the TiO2/g-C3N5 heterojunction materials with high specific surface area were constructed, and the S scheme charge transfer mechanism led to efficient photogenerated carrier separation, excellent redox activity, improved visible light absorption and broadened spectral response range. After visible light irradiation for 30 minutes, the TiO2/g-C3N5 (1:2) showed excellent photocatalytic activity, and the degradation rate of sulfamethylthiazole (STZ) reached 98.8%. STZ was degraded to small inorganic molecules such as H2O, CO2 and inorganic acids by a complex bond-breaking hydroxylation reaction under the attack of reactive groups such as ·O2−,·OH and h+. The S scheme charge transfer mechanism of TiO2/g-C3N5 heterojunction material was proposed through band potential analysis and density functional function (DFT) calculation.
