| 中文摘要: |
| 采用水热法制得了分别择优暴露{110}、{010}和{001}晶面的BiOBr.XRD研究结果显示,相应样品{110}与{102}衍射峰的强度之依次减小；可见光下BiOBr光催化降解环丙沙星的实验结果表明,BiOBr{110}、BiOBr{010}和BiOBr{001}上环丙沙星降解反应速率常数依次为0.008 9、0.001 2和0.000 9 min-1,即暴露的{110}晶面越多,其光催化降解环丙沙星的活性越高.BiOBr {110}晶面具有强的内电场,应是其高催化性能的内在原因. |

| The BiOBr samples with {110},{010} or {001} facets were obtained by hydrothermal methods.The results of XRD show that their intensity ratios of diffraction peak {110} to {102} decrease accordingly.The reaction rate constants of BiOBr{110},BiOBr{010} and BiOBr{001} for photocatalytic decomposing ciprofloxacin under visible light irradiation were 0.008 9,0.001 2 and 0.000 9 min-1,respectively.That is to say,the more the {110} facets exposed,the higher the photocatalytic efficiency of BiOBr.The strong internal electric field of BiOBr with {110} facets is shown to be the intrinsic factor for its high photocatalytic performance. |
