Nowadays, environmental pollution and energy shortage have aroused people‘s wide concern. Here we report that S‐doped BiOCl photocatalyst was successfully fabricated via a simple solvothermal process. The as‐obtained S‐doped BiOCl photocatalysts were investigated by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray photoemission spectroscopy (XPS), nitrogen adsorption‐desorption, UV/Vis diffuse reflectance (DRS), and photoluminescence (PL) emission spectra. The photocatalytic performance of the S‐doped BiOCl photocatalyst with different S contents was evaluated by the photocatalytic degradation of cationic dye (Rhodamine‐B (RhB)) and anionic dye (Congo red (CR)). The results reveal that all the S‐doped BiOCl samples possess better photocatalytic activity than pure BiOCl. Specifically, the degradation rate of S(6 %)‐BiOCl sample for RhB and CR was 99 % and 90 %, respectively. Meanwhile, the photocatalytic nitrogen fixation performance of the S‐doped BiOCl sample was investigated. The results show that the S(6 %)‐BiOCl sample possesses an excellent NH 3 yield of 108.6 μmol g −1 h −1 . Moreover, the S(6 %)‐BiOCl catalysts have excellent recyclability and stability. This work provides a facile and accessible pathway to design effective photocatalysts for both photocatalytic degradation and nitrogen fixation.
