A novel Bi₂WO₆/nano-ZnO hybrid material was synthesized by a simple two-step hydrothermal method for photocatalytic degradation of amoxicillin in wastewater under visible light. The material is a hybrid of nanosheets and like layered structure composed of many nanosheets. Compared with the pure Bi₂WO₆ and nano-ZnO, the photocatalytic activity of the photocatalytic materials Bi₂WO₆/nano-ZnO was significantly improved, and the Bi₂WO₆/nano-ZnO (molar ratio of Bi₂WO₆ and nano-ZnO: 1:3) sample had the highest photocatalytic activity for amoxicillin. It has been found that the improvement of photocatalytic activity is attributed to the reduction of band gap energy caused by the heterostructure formed by the two semiconductors, which can effectively separate the photo generated carriers and inhibit the recombination of photo generated charge carriers.

通过简单的两步水热法合成了一种新型Bi ₂ WO ₆ /纳米ZnO杂化材料，用于在可见光下光催化降解废水中的阿莫西林。该材料是纳米片和由许多纳米片组成的类似层状结构的混合体。与纯Bi ₂ WO ₆和纳米ZnO相比，光催化材料Bi ₂ WO ₆ /纳米ZnO的光催化活性显着提高，Bi ₂ WO ₆ /纳米ZnO（Bi ₂ WO _{6 的}摩尔比）和纳米 ZnO: 1:3) 样品对阿莫西林的光催化活性最高。研究发现，光催化活性的提高归因于两种半导体形成的异质结构导致带隙能量的降低，可以有效地分离光生载流子，抑制光生载流子的复合。
