BiOCl Nanosheets with Exposed Reactive {110} Facets Enhancing Photocatalytic Performance

利用溶剂热法可控制备了{110}晶面暴露的Bi OCl纳米微球并以甲基橙染料为目标污染物考察其光催化性能.利用XRD和SEM对纳米微球的晶体结构及形貌进行表征.通过与共沉淀法制备氯氧铋的光催化性能对比发现,在降解甲基橙溶液的过程中,高能晶面{110}暴露的Bi OCl纳米微球在紫外光和可见光下都展示出较高的光催化活性.

BiOClnanoparticles exposed {110} crystal were prepared by solvothermal method. The photocatalytic property of the samples was measured by decomposing the organic - dye of methyl orange. The crystal structure and morphology of nanoparticles were characterized by XRD and SEM techniques. Compared with the photocatalytic property of the samples by coprecipitation, high - energy {110} crystals of BiOCl nanoparticles were exposed, which showed high photodegradation efficiency under UV light irradiation and visible light irradiation.
