放电等离子烧结制备MoS2@Ni电极及其析氢反应性能
Preparation of MoS2@Ni Electrode by Spark Plasma Sintering and Its Performance in Hydrogen Evolution Reaction
摘要
Abstract
In order to solve the problem of complicated preparation steps and long period of hydrogen electrode during water decomposition,MoS2@Ni electrode was prepared by one-step spark plasma sintering process via nickel powder and different types of molybdenum sulfide powder as raw materials.When fine and uniform MoS2 powder and nickel powder were used,the overpotentials of the 0.03HS@C-Ni electrode were only 251 mV,322 mV,and 379 mV at current densities of 50 mA·cm-2,100 mA·cm-2 and 150 mA·cm-2,respectively,whereas the corresponding 0.03C@C-Ni electrodes with commercial MoS2 had overpotentials of 425 mV,488 mV,and 542 mV at current densities of 50 mA·cm-2,100 mA·cm-2 and 150 mA·cm-2,respectively,proving the catalytic performance of the electrode was good when fine and uniform MoS2 powder and nickel powder ware used.The stability and durability of 0.03HS@C-Ni electrode were tested.After 5000 cycles,the polarization curve of the electrode hardly changed.Even at a current density of 130 mA·cm-2,the electrode can work stably for more than 130 h.关键词
