摘要:

随着人类工业活动的不断加剧,化工、制药、印染、电镀等多个行业排放的废水已成为环境治理领域中亟待破解的重大课题,光催化技术是去除水中有机污染物的有效方法。Bi2WO6是具有可见光响应能力的光催化剂(带隙为2.7 eV),是由[Bi2O22+和[WO42-八面体层交替构成的二维奥里维里斯(Aurivillius)结构氧化物半导体,化学性质稳定,可在太阳光驱动条件下实现对有机污染物的降解。但其吸附和活化氧的能力有限、光生载流子复合率高、可见光响应范围窄(λ≤460 nm)等问题在一定程度上制约着其光催化综合性能的提升。围绕以上不足开展包括形貌调控、缺陷工程、元素掺杂、异质结构筑、金属粒子沉积在内的诸多改性研究。概述几种针对Bi2WO6材料改性的方法与机理,总结相关研究进展,针对不足展望未来可能的研究方向,为Bi系光催化剂材料的设计与改性研究提供借鉴。

Abstract:

With the intensification of human industrial activities,wastewater discharge from multiple sectors,including chemical manufacturing,pharmaceuticals,textile dyeing,and electroplating,has become a critical challenge requiring urgent resolution in environmental governance.Photocatalytic technology offers an effective approach for removing organic pollutants from water bodies.Bi2WO6 is a photocatalyst responsive to visible light(bandgap 2.7 eV),featuring a two-dimensional olivine-type oxide semiconductor structure composed of alternating[Bi2O22+ and [WO42- octahedral layers.This material exhibits chemical stability and can degrade organic pollutants under sunlight-driven conditions.However,its overall photocatalytic performance is constrained by limitations such as restricted adsorption capacity and reactive oxygen species generation,high recombination rates of photo-generated carriers,and a narrow visible light response range(λ≤460 nm).Numerous researchers have addressed these limitations through various modification strategies,including morphological control,defect engineering,elemental doping,heterostructure construction,and metal particle deposition.The several modification methods and mechanisms for Bi2WO6 materials were summarized,relevant research progress were systematically organized,and future research directions were proposed to overcome existing limitations.It was aimed to provide theoretical guidance for the design and modification of bismuth-based photocatalytic materials.

Key words: Bi2WO6, modification, mechanism, photocatalytic application
