A novel approach to prepare Bi2Fe4O9 flower-like spheres with enhanced photocatalytic performance

Abstract A novel two-step approach consisting of hydrothermal process and subsequently selective etching has been developed to prepare flower-like three-dimensional porous Bi2Fe4O9 spheres with good uniformity and highly photocatalytic performance. XRD patterns and SEM images reveal that the Bi2Fe4O...
