摘要
采用CS2-SDS-正辛醇-水微乳体系制备了硫化镉纳米棒。利用XRD、SEM、TEM对产物进行表征,测试了其对多硫化物电极还原反应的催化性能,并与常规方法合成的大粒度CdS晶体进行对比.结果表明,纳米棒为六方型CdS晶体,直径约12 nm.常规法合成的CdS为立方型晶体,平均粒度约为1μm.CdS纳米棒电极对硫化钠/多硫化钠电极反应的电催化活性明显高于大粒度CdS晶体电极.
The CdS nanorods were synthesized from the microemulsion system of CS2 - SDS - n-octanol - aqueous CdCl2. The final products were characterized using XRD, SEM and TEM. The electro-catalytic performance of the CdS nanorods was tested for sodium sulphide/ sodium polysulphide redox couple reaction. It has been shown that the CdS nanorods with average diameter about 12nm can be indexed as primitive hexagonal structure and they demonstrated better catalytic performance for the enhancement of the polysulfides reduction comparing to CdS bulks.
