| 摘 要： | 采用水热法制备了掺杂型可见光催化剂Ag-Bi2WO6,并对其进行X射线衍射（XRD）和紫外-可见光谱（UV-Vis DRS）表征手段对其结构性质进行了表征。以模拟含酚废水为目标物,研究了Ag-Bi2WO6光催化降解含酚废水的性能。表征结果表明,Ag的掺杂延伸了Bi2WO6的可见光吸收范围,吸收边带明显红移,能隙禁带宽窄于纯Bi2WO6,而Ag的掺杂没有改变Bi2WO6的晶相。在1.0 mg/LAg-Bi2WO6催化剂,20 m L/min空气流量,250 W金卤灯下,光催化反应150 min时,苯酚的降解率可达95%。

| Abstract: | The Ag- Bi2WO6 photocatalyst was synthesized by hydrothermal method. The chemical phase and optical absorption properties was characterized by XRD and Uv- Vis DRS. The photocatalytic activity of Ag- Bi2WO6 was researched by degrading phenols containing wastewater in visible light. The characterized results indicated that the doping Ag did not change the crystal phase of Bi2WO6,and the crystallinity of Ag- Bi2WO6 was better. The Ag-Bi2WO6 had a significant red- shift in the absorption band in the visible region,and the absorption intensity increased greatly for the doped catalyst. Under the conditions of 20 m L / min air flow,1. 0 mg / L catalyst amount,and150 min illumination time in 250 W metal halide light,the Ag- Bi2WO6 had a better desulfurization activity. |
