摘要
Abstract A novel two-step approach consisting of hydrothermal process and subsequently selective etching has been developed to prepare flower-like three-dimensional porous Bi 2 Fe 4 O 9 spheres with good uniformity and highly photocatalytic performance. XRD patterns and SEM images reveal that the Bi 2 Fe 4 O 9 phase does not exhibit any changes after the etching process, and the crystal morphology evolves from micro-platelets to flower-like three-dimensional porous Bi 2 Fe 4 O 9 spheres by controlling the experiment parameters. The change of morphology will lead to the significant increase of specific surface area, which would be beneficial to the enhancement of photocatalytic performance owing to prominent absorption in the ultraviolet and visible light region. As compared to Bi 2 Fe 4 O 9 microplatelets, flower-like three-dimensional porous Bi 2 Fe 4 O 9 spheres exhibit excellent photocatalytic degration rate of methyl orange (MO).
