摘要
本文报道了利用二相溶剂热法,以五水合硝酸铋和氯化钾为原料制备出BiOCl纳米片。利用了X射线粉末衍射(XRD)、透射电子显微镜(TEM)和紫外可见光谱仪(UV-vis)对样品的形貌、微观结构和光学性能进行了表征。分析结果显示样品为结晶性良好的四方相BiOCl纳米片,尺寸在50~100 nm。紫外可见光谱显示样品在紫外光范围内有很强的吸收能力。以甲基橙和亚甲基蓝为目标降解物来评估样品的光催化性能,结果显示,在紫外光的照射下两种染料在30分钟内分别可降解96.3%和97.7%,表明合成的样品具有优异的光催化降解染料的能力。
A two-phased solvothermal method was employed to synthesize BiOCI nanoplates using Bi（NO3）3·5H2O, sodium oleate and KCI as the starting materials. The phases, morphology and optical property of the products were characterized by X-ray powder diffraction （XRD）, transmission electron microscopy （TEM） and UV-vis diffuse reflectance spectroscopy （UV-vis）. XRD and TEM images showed that the BiOCl nanoplates have a tetragonal phase with the lateral length of 50-100 nm. UV-vis spectroscopy exhibited that the obtained BLOC1 samples have great absorption in the ultraviolet light range. Methyl orange （MO） and Methylene blue （MB） were used as the target degradation to assess the photocatalytic properties of the samples. Under UV irradiation, the degradation rate of MO and M B was approached to 96.3 % and 97.7 % within 30 min. The results indicated that the BiOC1 nanoplates have great potential applications in dye degradation.
