Agricultural runoff, fuel spillages, urbanization, hospitalization, and industrialization are some of the serious problems currently facing the world. In particular, byproducts that are hazardous to the ecosystem have the potential to mix with water used for drinking. Over the last three decades, various techniques, including biodegradation, advanced oxidation processes (AOPs), (e.g., photocatalysis, photo-Fenton oxidation, Fenton-like oxidation, and electrochemical oxidation process adsorption), filtration, and adsorption techniques, have been developed to remove hazardous byproducts. Among those, AOPs, photocatalysis has received special attention from the scientific community because of its unusual properties at the nanoscale and its layered structure. Recently, bismuth based semiconductor (BBSc) photocatalysts have played an important role in solving global energy demand and environmental pollution problems. In particular, bismuth-based Z-scheme heterojunction (BBZSH) is considered the best alternative route to overhaul the limitations of singlecomponent BBSc photocatalysts. This work aims to review recent studies on a new type of BBZSH photocatalysts for the treatment of contaminated water. The general overview of the synthesis methods, efficiencyenhancing strategies, classifications of BBSc and Z-scheme heterojunctions, the degradation mechanisms of Z-and S-schemes, and the application of BBZSH photocatalysts for the degradation of organic dyes, antibiotics, aromatics compounds, endocrinedisrupting compounds, and volatile organic compounds are reviewed. Finally, challenges and the future perspective of BBZSH photocatalysts are discussed.

“…Besides BiOCl and BiOBr, flower-like BiOI/Bi 2 WO 6 microspheres were prepared via the hydrothermal route for the degradation of phenol [81]. The formed heterojunction between Bi 2 WO 6 and BiOI enhanced the separation efficiency of the electron and hole, further improving the photocatalytic activity.…”

With the rapid development of modern industries, water pollution has become an urgent problem that endangers the health of human and wild animals. The photocatalysis technique is considered an environmentally friendly strategy for removing organic pollutants in wastewater. As an important member of Bi-series semiconductors, Bi2WO6 is widely used for fabricating high-performance photocatalysts. In this review, the recent advances of Bi2WO6-based photocatalysts are summarized. First, the controllable synthesis, surface modification and heteroatom doping of Bi2WO6 are introduced. In the respect of Bi2WO6-based composites, existing Bi2WO6-containing binary composites are classified into six types, including Bi2WO6/carbon or MOF composite, Bi2WO6/g-C3N4 composite, Bi2WO6/metal oxides composite, Bi2WO6/metal sulfides composite, Bi2WO6/Bi-series composite, and Bi2WO6/metal tungstates composite. Bi2WO6-based ternary composites are classified into four types, including Bi2WO6/g-C3N4/X, Bi2WO6/carbon/X, Bi2WO6/Au or Ag-based materials/X, and Bi2WO6/Bi-series semiconductors/X. The design, microstructure, and photocatalytic performance of Bi2WO6-based binary and ternary composites are highlighted. Finally, aimed at the existing problems in Bi2WO6-based photocatalysts, some solutions and promising research trends are proposed that would provide theoretical and practical guidelines for developing high-performance Bi2WO6-based photocatalysts.

“…Considering the similar crystal structures of Bi 2 WO 6 and BiOCl, a Bi 2 WO 6 /BiOCl heterojunction has been developed to enhance their photocatalytic activity. 28,29 The high photocatalytic performance of a Bi 2 WO 6 /BiOCl heterojunction can be ascribed to the following three aspects: (i) the same [Bi 2 O 2 ] 2+ layer enables lattice matching and the formation of a two-dimensional heterojunction; (ii) the combination of a layered structure strengthens the surface/ interfacial contact to accelerate charge transfer; (iii) the construction of a heterojunction adjusts the band gap to enhance the light absorption capability. Among existing reports, BiOCl/ Bi 2 WO 6 heterojunctions are usually fabricated via a one-step hydrothermal method, or BiOCl is synthesized first, before being loaded with Bi 2 WO 6 .…”
