Abstract:

The ZnMgAl hydrotalcite-like compounds(HTLCs) supported bismuth oxyiodide(BiOI)(BiOI/ZnMgAl-HTLCs) visible light photocatalyst was prepared by hydrothermal method. The effects of BiOI loading mass fraction, reaction temperature, reaction time, and addition sequence on the structure and morphology of the BiOI/ZnMgAl-HTLCs photocatalyst were investigated by X-ray diffraction(XRD), scanning electron microscopy(SEM) and Fourier transform infrared spectroscopy(FTIR). The results show that BiOI/ZnMgAl-HTLCs with high crystallinity and good morphology can be obtained by firstly adding BiOI in 40% mass fraction to ZnMgAl-HTLCs at 140 ℃, and keeping reaction for 24 h.
