摘　　要：采用醇热法以Bi(NO3)3.5H2O、TiCl3和无水乙醇为原料合成了BiOCl微米球光催化剂.通过X射线衍射仪(XRD)、扫描电镜(SEM)和紫外-可见分光光度计(UV-vis)对样品进行表征,并估算出能隙大小约为2.58eV.结果表明,该样品为球状物并且在降解染料上具有良好的效率,65min以内对罗丹明B(RhB)的脱色率高达94%以上,优于P25在紫外光下的催化效果.The BLOCl microspheres were prepared by one-step alcohol-heating process using Bi （NO3）3 · 5H2O, TiCl3 and absolute ethanol. The sample was characterized by XRD, SEM, UV-vis DRS, and the bandgap was estimated to be 2.58 eV. The results of the study show that the sample is microspheres; and it has excellent efficiency that could degradate more than 94% of RhB in 65 minites, which means that, in photocatalytic reactions of Rhodamine B（RhB） dye degradation, BLOCl has better performance than TiO2 （P25） under UV irradiation.
