【摘要】 采用熔盐法在不同的温度（350～400℃）快速合成BiVO₄,并对合成的样品进行形貌、结构和光催化性能研究.利用X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶红外光谱（FT-IR）、紫外-可见漫反射光谱分析（DRS）、比表面积（BET）、荧光光谱（PL）等手段对BiVO₄光催化剂的结构、形貌和荧光性质进行了表征,并在可见光下降解罗丹明B来研究BiVO₄光催化性能.实验结果表明,370℃时制备的BiVO₄光催化剂光催化效果最好,在120min的可见光的照射下,86.8%的罗丹明B被降解.更多还原

【Abstract】 BiVO₄ was rapidly synthesized by a molten salt method at different temperatures（350～400 ℃）, and the morphology, structure and photocatalytic properties of the synthesized samples were studied. The structure, morphology and fluorescence properties of BiVO₄ photocatalyst were characterized by X-ray diffraction（XRD）, Scanning electron microscope（SEM）, Fourier infrared spectrum（FT-IR）, Uv-vis diffuse reflection spectroscopy（DRS）, Specific surface area（BET） and Fluorescence spectroscopy（PL）. In addition, the degradation performance of BiVO₄ photocatalyst on rhodamine B solution under visible light was also studied. The results showed that the BiVO₄ photocatalyst fabricated at 370 ℃ had the best photocatalytic effect, and the degradation rate of rhodamine B was 86.8% at 120 min under visible light.更多还原
