摘要
以Bi(NO_(3))_(3)·5H_(2)O为Bi源、十六烷基三甲基溴化铵(CTAB)为Br源和表面活性剂、无水乙酸为溶剂和螯合剂,采用溶剂热的方法成功制备了形貌可控的C掺杂BiOBr(C-BiOBr)。利用XRD、SEM、TEM、BET、XPS、PL和UV-Vis等对其进行表征,并以环丙沙星(CIP)作为模拟污染物评价催化剂的性能。结果表明,所制备的样品禁带宽度均比纯BiOBr(2.7 eV)明显缩减,光催化性能较好,重复利用性更强。
Using Bi(NO_(3))_(3)·5 H_(2)O as Bi source, cetyltrimethyl ammonium bromide(CTAB) as Br source and surfactant, anhydrous acetic acid as solvent and chelating agent, the morphology-controllable carbon-doped BiOBR(C-BiOBR) is successfully prepared via a solvothermal method.The samples are characterized by XRD,SEM,TEM,BET,XPS,PL and UV-Vis, and their performances are evaluated with ciprofloxacin(CIP) as a simulated pollutant.It is shown that the band gap of the prepared samples is significantly narrow than that of pure BiOBr(2.7 eV),the photocatalytic performance is better, and the reusability is stronger.
