· JVASP-57379· Bi2WO6

Bismuth tungstate (Bi₂WO₆) is a complex oxide ceramic compound belonging to the family of layered perovskite-related materials. This material is primarily studied in photocatalytic and photoelectrochemical applications, where its semiconducting properties and band structure make it attractive for environmental remediation and energy conversion under visible light. Bi₂WO₆ is notably used in water purification, air pollutant degradation, and emerging photocatalytic fuel generation, offering advantages over traditional titania-based catalysts due to its narrower band gap and reduced dependence on UV radiation.
