摘要
以六水合硝酸钴(Co(NO_3)_2·6H_2O)为钴源,硫脲(CS(NH_2)_2)为硫源,采用溶剂热法和低温固相硫化的方法制备出了介孔Co_3S_4纳米棒。采用X射线衍射(XRD),扫描电镜(SEM)和透射电镜(TEM)等手段对于介孔Co_3S_4纳米棒进行表征,同时对介孔Co_3S_4纳米棒进行了电催化产氧性能测试。结果表明:介孔Co_3S_4纳米棒的起始过电位为0.37 V,塔菲尔斜率为76.95 m V/dec,具有高的电催化产氧性能。
The mesoporous Co3S4 nanorods were synthesized by the solvent-thermal method and low- temperature vulcanization, using cobalt nitrate thhexahydrate （ Co （ NO3 ） 2 ·6H2 O） as cobalt source and thiourea（ CS （NH2 ）2 ） as sulfur source. Mesoporous Co3S4 nanorods were characterized by X-ray diffraction （ XRD）, scanning electron microscopy （SEM） and transmission electron microscopy （ TEM ）. The electrocatalystic performance of mesoporous Co3S4 nanorods was investigated. The results indicate that mesoporous Co3 S4 nanorods show high electrocatalyst activity which have low onset potential 0.37 V and Tafel slope 76.95 mV/dec.
