摘要：
Flower-like porous Bi5O7I was successfully synthesized through an easy thermal decomposition of flower-like BiOI. And its chemical structure, morphology and optical property were thoroughly analyzed by x-ray diffraction, x-ray photoelectron spectroscopy, scanning electron microscope, energydispersive spectrometry elements mapping, transmission electron microscopy, N-2 adsorption-desorption isotherm, BET, andUV-vis diffuse reflectance spectra. The visible-light photocatalytic elimination of rhodamine B (RhB) was investigated. The experimental results indicated that flower-like porous Bi5O7I exhibited enhanced photocatalytic activity for degrading RhB in comparsion of flower-like BiOI, g-C3N4 and N-doped TiO2. Additionally, the as-prepared flower-like porous Bi5O7I possessed catalytic stability after recycles.
