为了提高催化剂的光催化产氢能力,本文采用简单的水热法,在处理后的钛网表面生长了CdS纳米微球.利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和X射线光电子能谱(XPS)等测试手段对样品的成分、结构、形貌进行了表征,并研究了其光电化学性能及可见光下光催化性能.结果表明,钛网上生长的CdS微球由纳米棒组装而成,通过缺陷调控,Cd/S物质的量之比为1∶1(CdS-1)的样品具有良好的光电响应,在零偏压下最大光电流约为140 μA,可见光下的产氢率可达212.6 μmol·h-1·cm-2,并且方便回收,是一种理想的光催化产氢材料.
Preparation of CdS Nanospheres on Titanium Meshes with Photocatalytic H2 Evolution under Visible Light
It is an interesting topic to improve the photocatalytic H2 evolution activities of catalysts.In this parper,CdS nanospheres on titanium meshes have been synthesized by a simple hydrothermal method.The composition,microstructure and morphology of samples were investigated using X-ray diffractometer(XRD),scan electron microscopy(SEM),transmission electron microscope(TEM)and X-ray photoelectron spectroscopy(XPS).And the photoelectrochemical properties and photocatalytic properties under visible light were studied.The results show that,each CdS nanosphere on titanium meshes is self-assembled with nanorods.Then,the samples were used as photoelectrochemical photoanodes and photocatalytic water-splitting processes,the sample with a Cd/S amount of substance ratio of 1∶1(CdS-1)has a good photoelectric response,and has a maximal photocurrent of～140 μA.At the same time,the results show that the sample has a good H2 evolution activity with the rate of 212.6 pmol·h-1·cm-2 and recycling convenient,reusable,which can be an ideal photocatalyst.
