A Hierarchically Porous Hollow Structure of Layered Bi2TiO4F2 for Efficient Photocatalysis

摘要: Bismuth compounds have been greatly spurred due to their extensive applicaton in photocatalysis which is a promising technique for environmental decontamination. In this research, Bi2TiO4F2 hierarchically porous hollow spheres are successfully prepared by simple solvothermal method. X-ray powder diffraction patterns show that the sample has an Aurivillius-type layered perovskite structure. The electron microscopy analyses reveal obtained hierarchical surface composed of interlaced nanoplates. formation and growth mechanisms product proposed based on time-dependent evolution experiments. band gap measured about 2.85 eV. photocatalytic activity systematically explored. results demonstrate can be effectively served as catalyst degradation Rhodamine B methyl orange under UV-light irradiation via reaction, also used visible-light photosensitization process.
