摘要:
通过在BiVO4水热合成过程中改变形貌控制剂乙二胺四乙酸(EDTA)或十六烷基三甲基溴化铵(CTAB),调节BiVO4的形貌,暴露活性晶面。加入葡萄糖,引入C量子点(CQDs),进一步提高其可见光催化裂解水性能。用场发射扫描电子显微镜(FESEM)、高分辨率透射电子显微镜(HRTEM)和X线衍射仪(XRD)分别对样品进行形貌与物相结构的表征。结果表明:当形貌控制剂为EDTA时,C量子点修饰的暴露活性晶面的BiVO4纳米片被成功合成,该纳米片宽度为0.7~10 μm,厚度约为100 nm; 当葡萄糖的量为1 g时,所制得样品具有很强的可见光催化性能,是没有C量子点修饰样品的7倍。
Abstract:
With choosing ethylene diamine tetraacetic acid(EDTA)or cetyltrimethyl ammonium bromide(CTAB)as capping agents,the morphology of BiVO4 was regulated to expose active facets.By adding glucose during the preparation of BiVO4,the C quantum dots(CQDs)were introduced to improve the performance of visible photocatalytic water cleavage.Field emission scanning electron microscope(FESEM),high resolution transmission electron microscope(HRTEM)and X-ray diffraction(XRD)were used to investigate the morphology and phase structure of the prepared samples.Results showed that when EDTA was used,the C quantum dot modified BiVO4 nanosheets with active facets were successfully synthesized.The nanosheets had the width of 0.7-10 μm and the thickness of 100 nm.When the amount of glucose was 1 g,the sample had the better visible photocatalytic activity,which was 7 times that of the sample without C quantum dots.
