Bi_(2)WO_(6)光催化材料研究进展

Research Progress in Bi_(2)WO_(6) Photocatalytic Materials

光催化技术作为环境友好型技术,受到研究者广泛关注。Bi_(2)WO_(6)作为一种物化稳定的、无毒无害的可见光催化材料,在能源、环境和化学合成等领域得到广泛研究。对于纯的Bi_(2)WO_(6),其吸收太阳光的能力有限,光生载流子易复合,造成光催化性能受限。通过对Bi_(2)WO_(6)进行形貌控制、掺杂/制备固溶体以及与其他材料构建异质结等方式,可提高材料的光催化性能。综述Bi_(2)WO_(6)材料的基本性质以及改性方法,为推动Bi_(2)WO_(6)基光催化剂发展提供一定借鉴。

Photocatalytic technology,as an environmentally friendly technology,has received extensive attention from researchers.Bi_(2)WO_(6),as a physically and chemically stable,non-toxic and harmless visible photocatalytic material,has been widely studied in the fields of energy,environment and chemical synthesis.For pure Bi_(2)WO_(6),its ability to absorb sunlight is limited and the photo generated carriers are prone to complexation,resulting in restricted photocatalytic performance.The photocatalytic performance of Bi_(2)WO_(6) can be improved by controlling the morphology of Bi_(2)WO_(6),doping/preparing solid solutions,and constructing heterojunctions with other materials.The basic properties of Bi_(2)WO_(6) materials and the modification methods are reviewed to provide some reference for promoting the development of Bi_(2)WO_(6)-based photocatalysts.
