摘要
具有高附加值的绿色环保型氧化剂——过氧化氢(H_(2)O_(2))的需求日益增加,急需发展绿色且安全的H_(2)O_(2)合成新方法。两电子氧还原反应(2e-ORR)是一种制备H_(2)O_(2)的高效方法,其中催化剂的高效率和高选择性是2e-ORR的关键。对二硒化钴(CoSe_(2))电催化剂的制备和性能测试实验进行了探索。首先,通过联氨还原法制备钴纳米粒子;然后,通过简单的固相反应并在不同温度下退火制备CoSe_(2)电催化剂;最后,通过一系列的表征方法对CoSe_(2)电催化剂的表面形貌、晶型、电化学及其稳定性等进行了研究。为2e^(-)ORR电催化剂CoSe_(2)的进一步研究和应用开发提供借鉴。
With the increasing demand of highly value-added and environment-friendly oxidant hydrogen peroxide(H_(2)O_(2)),it is urgent to develop a new green and safe synthesis method of H_(2)O_(2).Two-electron oxygen reduction reaction is an efficient method to prepare H_(2)O_(2),in which the high efficiency and selectivity of catalyst is the key factors for 2e-ORR.The preparation and performance test of cobalt diselenide(CoSe_(2))electrocatalyst were investigated in this paper.Firstly,cobalt nanoparticles were prepared by hydrazine reduction method.Then,CoSe_(2) electrocatalyst was prepared by simple solid phase reaction and annealing at different temperatures.Finally,the surface morphology,crystal phase,electrochemistry and stability of CoSe_(2) electrocatalyst were studied by a series of characterization methods.This work will benefit the further research and application of 2e^(-)ORR electrocatalyst CoSe_(2).
