Abstract
Defective tungsten oxides (WO3−x) with oxygen vacancies (OVs) are recognized for exceptional photocatalytic properties attributed to their unique electronic structures, abundant OVs, and local surface plasmon resonance effect. There has been a growing research interest in developing OV-rich WO3−x as efficient photocatalysts for applications in environmental remediation and energy conversion. This review covers various available approaches for synthesizing WO3−x, including hydrothermal, solvothermal, microwave, and template methods. It also focuses on recent progresses on several modification strategies, such as ion doping, metal deposition, morphology control, heterojunction construction, and single-atom engineering, for maximizing the photocatalytic efficiency of WO3−x. The correlation between photocatalytic activity, chemical compositions, morphological characteristics, and textural properties of catalysts is highlighted. The application of these WO3−x photocatalysts with improved performances in the fields of wastewater treatment, H2 evolution, CO2 reduction, N2 fixation, photoelectrochemical catalysis, and stability is discussed. Finally, prospects and challenges in the synthesis and application of WO3−x-based photocatalysts are outlined.
