水热法制备VC/CdSe光催化剂及其产氢性能研究
Preparation of VC/CdSe photocatalysts via hydrothermal method and study on their hydrogen production performance
Vanadium carbide-modified cadmium selenide photocatalysts (VC/CdSe) are successfully prepared via the hydrothermal method.Multiple characterization techniques,including X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FT-IR),X-ray photoelectron spectroscopy (XPS),scanning electron microscopy (SEM),diffuse reflectance spectroscopy (DRS),and Brunauer-Emmett-Teller (BET) analysis,are employed to analyze the physicochemical properties of VC/CdSe photocatalysts,while their photocatalytic hydrogen production performance is explored.Results show that VC/CdSe photocatalyst with a optimized VC loading amount exhibit excellent hydrogen production performance under the irradiation of a xenon lamp,with Na2S/Na2SO3 as the sacrificial agent.The hydrogen production rate over VC-10/CdSe reaches as high as 38.71 mL/h,which is approximately 52 times that over pure CdSe,indicating that there is a good synergistic effect between VC and CdSe,and a heterojunction structure is formed between them.
