  • 摘要: 采用低温水热法制备掺杂MoO3的WO3粉体,利用XRD,XPS,DRS和PL光谱对产物进行表征,以太阳光为光源对番红花红T溶液进行光催化降解研究.结果表明:MoO3掺杂含量为10%的WO3粉体对番红花红T溶液的脱色率为89.65%,COD去除率为88.9%.借助DRS和PL光谱分析结果,初步探讨了MoO3掺杂WO3粉体对番红花红T光催化降解的过程与机理.
    Abstract: WO3 powders doped with MoO3were successfully prepared by the hydrothermal method. The products were characterized via X-ray powder diffraction(XRD),X-ray photoelectron spectroscopy(XPS)analysis,UV-Vis diffused reflectance spectra (DRS) and photoluminescence (PL) spectrum. The photocatalytic degradation of safranin T in MoO3/WO3 products under sunlight was studied. The results showed that the decoloration rate of safranin T in 10% MoO3/WO3 sample was 89.65%,and the removal rate of chemical oxygen demand (COD) was 88.9%. Moreover,by means of the analytical results of DRS and PL spectrum,the photocatalytic degradation process and mechanism of safranin T in MoO3/WO3 samples were tentatively discussed.
