【摘要】 采用水热法将碘氧化铋(BiOI)负载到锌镁铝类水滑石(ZnMgAl-HTLCs)上制备得到BiOI/ZnMgAlHTLCs可见光催化剂。通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FTIR)等技术手段考察了BiOI负载质量分数、反应温度、反应时间及加料顺序等因素对BiOI/ZnMgAl-HTLCs光催化剂结构及形貌的影响。结果表明,在制备BiOI/ZnMgAl-HTLCs材料中先加入锌镁铝类水滑石,负载质量分数为40%的BiOI,反应温度为140℃,反应时间为24 h,可以得到结晶度高和形貌较好的BiOI/ZnMgAl-HTLCs。更多还原

【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/ZnMgAlHTLCs 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.更多还原
