| 摘 要： | 采用水热法合成了可见光催化剂Cu-BiVO4，并对其进行X射线粉末衍射（XRD）、紫外-可见漫反射 (UV-Vis DRS)表征。以噻吩的正辛烷溶液模拟轻质油品为目标物，以催化剂的pH值、用量、光照时间、通气量等工艺条件为考察对象，研究了Cu-BiVO4光催化氧化去除模拟汽油中硫化合物的性能。结果表明，Cu的复合使BiVO4的可见光吸收带发生红移，吸收强度也有较大幅度的提高。在中性条件下制备的催化剂的活性最高，在空气通入量为300mL/min，催化剂加入量为0.5mg/L时， 400W金卤灯照射180min，Cu-BiVO4光催化氧化脱硫效果较好，模拟汽油的脱硫率可达到95%以上。

| Abstract: | A type of visible light catalysis Cu-BiVO4 is prepared by hydrothermal method and characterized by UV-vis DRS and XRD. Using the thiophene in octane as the simulation of model sulfur compounds, the desulfurization activity of Cu-BiVO4 was researched by photocatalytic oxidation in visible light. The effects of pH of catalysts prepared, irradiation time, photocatalyst Cu-BiVO4 mass, air flow on the desulfurization efficiency were also investigated. The results show that the Cu-BiVO4 catalyst has a significant red-shift in the absorption band in the visible region, and the absorption intensity increases greatly for the composite catalyst. Under suitable conditions, the desulfurization rate of Cu-BiVO4 to the model compound can reach 95%. |
