Abstract：With bulk g-C3N4 as a raw material, S-doped g-C3N4 photocatalyst (SCNB-18) with tubular multi-pore channels were obtained by one-step hydrothermal method using thioacetamide (TAA) as a sulfur source. The introduction of S expanded the visible light absorption range of g-C3N4, and the tubular porous morphology increased the specific surface area of nanocatalyst. Compared with bulk g-C3N4, SCNB-18 possessed a larger surface area of about 170.6 m2/g. Moreover, the microstructure and photoelectric properties for the samples were characterized. The catalytic performance of SCNB-18 was evaluated by photocatalytic hydrogen production and degradation of pollutants. The results showed that SCNB-18 nanocatalyst exhibited an excellent photocatalytic performance and cyclic stability.
