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［Bi2O2］2+ and ［WO4］2- 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
