【摘要】 近些年,Bi₂WO₆作为一种新型、绿色、安全的光催化剂走进了人们视野,又因其较窄的禁带宽度和类钙钛矿层状结构可有效地提高太阳光利用率而成为研究热点.通过控制催化剂的制备条件以控制其形貌进而改善催化性能是Bi₂WO₆的一个主要研究方向.本文结合Bi₂WO₆几种制备方法,对所制成材料的形貌和降解能力作简要介绍,并对今后的研究前景作出展望,以期Bi₂WO₆在废水中难降解有机物的处理方面有更好的应用和发展.更多还原

【Abstract】 In recent years, Bi₂WO₆ has entered people’s field of vision as a new, green and safe photocatalyst. It has become a research hot spot because of its narrow forbidden band width and perovskite-like layered structure which can effectively improve the utilization rate of sunlight. Controlling the preparation conditions of the catalyst to control its morphology and thus improve its catalytic performance is one of the main research directions of Bi₂WO₆. Combining several aspects of Bi₂WO₆, the morphology and degradation ability of the materials are introduced, and the future research prospect is prospected. It is expected that Bi₂WO₆ will have better application and development in the treatment of refractory organics in wastewater.更多还原
