摘要
利用简单的溶剂热法成功制备出分等级花状Bi OBr.利用X射线衍射(XRD)、扫描电子显微镜(SEM)、氮气吸附-脱附分析和紫外-可见漫反射光谱(UV-Vis DRS)对样品的晶体结构、形貌、孔结构和光学性质进行了表征.实验结果表明,制备的Bi OBr为纳米片组装成的微米花.在室温下研究了花状Bi OBr对罗丹明B的光催化活性,结果表明该样品可见光照射下能有效降解罗丹明B,25 min降解率可达到100%.
The hierarchical flower-like BiOBr were successfully synthesized by a facile solvothermal method.The crystal structure,morphology,pore structure and optical properties of as-fabricated sample were characterized systematically by X-ray diffraction(XRD),scanning electron microscopy(SEM),brunauer-emmett-teller(BET)and UV-vis diffuse reflectance spectroscopy(DRS).The results indicated that the obtained BiOBr sample was hierarchical microflowers self-assembling with ultrathin nanosheets.The photocatalytic activity of the obtained sample for RhB under the visible irradiation was investigated.The results reveal that the sample exhibits a significantly enhanced photocatalytic performance,and the degradation rate reaches 100%in 25 minutes.
