2D laminated cylinder-like BiFeO3 composites: Hydrothermal preparation, formation mechanism, and photocatalytic properties

The novel nanostructures BiFeO3 composites have been successfully prepared via a hydrothermal method. The BiFeO3 photocatalyst had a remarkably enhanced photocatalytic activity, which is ascribed to the large numbers of oxygen vacancies and unique 2D laminated cylinder-like morphology nanostructures, and h+ was the main reactive species for the photocatalytic process.
