MoS2/CNTs/Ni3S2纳米复合催化剂的制备及电催化性质
Preparation and electrocatalytic properties of MoS2/CNTs/Ni3S2 nanocomposite catalysts
【摘要】 利用两步溶剂热法在泡沫镍上原位生长了MoS2/CNTs/Ni3S2异质结构（MCN）电极，并对其电催化性质进行了研究．在10 mA/cm2的电流密度下，该电极的HER过电势为135 mV;在50 mA/cm2的电流密度下，其OER过电势为313 mV．利用该复合型电催化剂组装的电解池用于全解水时，驱动10 mA/cm2的电流密度仅需要1.47 V电压．
【Abstract】 MoS2/CNTs/Ni3S2 heterostructures（ MCN） were grown in situ on foam nickel by a two-step solvothermal method,and their electrocatalytic properties were investigated. At the current density of 10 mA/cm2,the overpotential of MCN for HER was only 135 mV. At the current density of 50 mA/cm2,the overpotential of MCN for OER was 313 mV. In addition,the dual electrode electrolytic cell assembled with this composite material only required a voltage of 1. 47 V to drive a current density of 10 mA/cm2 for overall water splitting.
