球状纳米BiOCl光催化剂的合成和光催化性能研究

Synthesis and Photocatalytic Properties of Spherical BiOCl Nanoparticles

以Bi（NO3）3·5H2O和KCl为原料,乙二醇为溶剂,通过溶剂热法合成了BiOCl系列材料,同时对BiOCl进行了XRD和SEM表征,表征结果表明经溶剂热法合成的BiOCl产品纯净,形貌为1.5-4.0μm的球状结构。实验表明,BiOCl的最佳合成条件为：合成时间10h,合成温度160℃,该条件下得到的BiOCl对罗丹明B的降解率在15min时达到97.38%。

Spherical BiOC1 were prepared by solvothermal method using Bi（NO3 ）3 · 5 H2O and KCl as raw materials, glycol as solvent. The prepared BiOCl were characterized hy XRD and SEM, showing that the as-synthesized product is pure BiOCl and consists of 1.5--4. 0 μm spherical structure. The optimum synthetic conditions are as follows; synthesis time 10 h, sintering temperature 160 ℃ ,with which the prepared BiOCl has the best degradation rate toward rhodamine B reaches 97.38% in 15 min.
