PVP assisted hydrothermal fabrication and morphology-controllable fabrication of BiFeO3 uniform nanostructures with enhanced photocatalytic activities

Bismuth ferrite (BiFeO3) nanostructures with various morphologies (spindles, cubes and plates) have been successfully synthesized via a convenient one-pot hydrothermal method. The results show that three kinds of BiFeO3 products were obtained in this polyvinylpyrrolidone (PVP)-assisted hydrothermal reaction under different alkaline conditions. The resulting nanostructures were characterized using XRD and SEM. Possible formation mechanism for...
