BiPO4/ZnWO4的制备及光催化性能研究
Preparation of BiPO4/ZnWO4 and its visible light catalytic performance
为了提高ZnWO4光催化活性，制备了BiPO4@ ZnWO4复合光催化剂，利用X 射线衍射仪、扫描电子显微镜、比表面积和孔径分析仪、傅里叶红外光谱对光催化剂进行了表征，采用电化学工作站对催化剂的光电化学性质进行了测试分析，结果表明实验制备出了晶型结构完整的BiPO4@ZnWO4光催化剂； BiPO4附着在ZnWO4纳米片表面，增大了其比表面积。在可见光的照射下，20%BiPO4@ZnWO4的瞬时光电流高于ZnWO4，这表明BiPO4@ZnWO4对e-?h+有较强的光吸收和分离效率。对所合成的催化剂进行了可见光光催化降解试验，结果表明，BiPO4复合比例为20wt%，催化剂用量为50 mg时，对10 mg/L的罗丹明B溶液降解率达到99%，而单项ZnWO4为70%。?????
in order to improve the photocatalytic activity of BiPO4@ZnWO4, BiPO4@ZnWO4 composite photocatalyst was prepared, and the photocatalyst was characterized by XRD, SEM, BET and FTIR. The photoelectrochemical properties of the catalyst were tested and analyzed by electrochemical workstation. The results show that the photocatalyst with complete crystal structure has been prepared. BiPO4 is attached to the surface of ZnWO4 nanowires, which increases its specific surface area. Under the irradiation of visible light, the instantaneous photocurrent of 20% BiPO4@ZnWO4 is higher than that of ZnWO4, which indicates that BiPO4@ZnWO4 has higher light absorption and higher separation efficiency for e--Preparation of BiPO4/ZnWO4 and its visible light catalytic performanceh+. The compound ratio of BiPO4 was 20wt%, and when the amount of catalyst was 50mg, the degradation rate of rhodamine B solution of 10mg/L was 99%, while the single ZnWO4 was 70%.?????
