Recent advances on Bi2WO6-based photocatalysts for environmental and energy applications

Bismuth tungstate (Bi2WO6) has become a research hotspot due to its potential in photocatalytic energy conversion and environmental purification. Nevertheless, the limited light absorption fast recombination of photogenerated carriers hinder further improvement performance Bi2WO6. Herein, we provide systematic review for recent advances on Bi2WO6-based photocatalysts. It starts with crystal structure, optical properties fundamentals Then, focus modification strategies Bi2WO6 based morphology control, atomic modulation composite fabrication diverse applications, such as organic synthesis, water splitting, CO2 reduction, treatment, air purification, bacterial inactivation, etc. Finally, some current challenges future development prospects are proposed. We expect that this can useful reference guidance efficient
