摘要:

以硝酸铋和咪唑盐酸盐为原料,分别以水和无水乙醇为溶剂通过简单搅拌合成了BiOCl微球。采用X射线衍射仪、扫描电子显微镜、紫外-可见漫反射吸收光谱和比表面分析等手段对样品的晶型、形貌、光学性能等进行了考察。以罗丹明B为目标降解物考察了溶剂对BiOCl形貌和光催化性能的影响。结果表明,水中合成的BiOCl具有较好的结晶度和较高的光催化性能,120min内对罗丹明B的降解率为95%。乙醇中合成的BiOCl尽管具有较大的表面积,但降解罗丹明B的能力弱于水中合成的BiOCl,120min内对罗丹明B的降解率为87%。溶剂介电常数的不同可能是造成催化效果差异的原因。

BiOCl microspheres were prepared by a simple mixing method with water and ethanol as solvents as well as bismuth nitrate and imidazole-hydrochlorideas as raw materials. The phase, morphologies and optical properties of the as-prepared BiOCl were characterized by scanning electron microscopy, X-ray diffraction, UV-Visible diffuse reflectance spectroscopy and specific surface area analysis, respectively. The effect of solvent on the morphologies and photoactivity of BiOCl was investigated via the degradation of rhodamine B (RhB) under UV irradiation. The results show that the better crystallinity and the higher photocatalytic activity of BiOCl can be obtained when water is used as a solvent, and the degradation rate for  RhB within 120min reaches 95%. BiOCl prepared in ethanol has a greater specific surface area. The degradation ability of RhB is lower than that of BiOCl prepared in water, and the degradation rate for RhB within 120min reaches 87%. The dielectric constant difference between water and ethanol may cause the various catalytic activities.
