Preparation and Catalytic Performance of S-Doped Tubular Porous g-C3N4 Photocatalysts
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.
