【摘要】 氧化铋（Bi₂O₃）作为重要的半导体光催化材料,由于特殊的电子结构和优良的可见光响应性能,被认为是一种很有前景的可见光光催化剂,在光催化处理废水方面显示了良好的应用前景。但因Bi₂O₃光催化性能较低限制了它的应用,因此研究者对其进行改性,期望获得性能优越的Bi₂O₃光催化材料。综述总结了表面形貌调控、表面修饰、金属离子修饰以及半导体复合等几种改性方法,并对改性Bi₂O₃光催化材料的发展前景进行了展望。更多还原

【Abstract】 As an important semiconductor photocatalytic material, bismuth oxide（Bi₂O₃） is considered as a promising visible photocatalyst due to its special electronic structure and excellent visible light response performance. It displays a good application prospect in photocatalytic treatment of wastewater. However, the application of Bi₂O₃ is limited by its low photocatalytic performance, therefore, Bi₂O₃ pholocatalyst with superior performance is expected to be obtained by modifying methods by the researchers. In this review, a series of modification methods, such as surface morphology regulation, surface modification, metal ion modification and semiconductor combination, are summarized. Then, the future development of modified Bi₂O₃ photocatalytic materials is prospected.更多还原
