Preparation of MoS2-PEDOT@Ni F composite and its electrocatalytic hydrogen evolution performance

本实验主要研究的是二硫化钼(MoS2)与聚(3,4-乙烯二氧噻吩)(PEDOT)长在泡沫镍(Ni F)上形成MoS2-PEDOT@Ni F复合材料的电化学性质。使用钼酸钠、巯基乙酸(TGA)为原料制备MoS2@Ni F,然后再与3,4-乙烯二氧噻吩单体(EDOT)进一步反应聚合在泡沫镍上,制备出MoS2-PEDOT@Ni F复合材料。通过初步探索,确定了最佳条件为,钼酸钠:0.048g,反应温度200℃,反应时间10h。通过对MoS2@Ni Foam和MoS2-PEDOT@Ni F复合材料进行了扫描电子显微镜(SEM)、能谱(EDS)、X射线衍射(XRD)、X射线光电子能谱(XPS)表征。用电化学工作站对MoS2@Ni F、PEDOT@Ni F和MoS2-PEDOT@Ni F复合材料进行极化曲线、阻抗和稳定性的测试。结果表明所合成的复合材料具有很好的析氢催化能力。

In this study,this experiment is mainly about the electrochemical properties of molybdenum disulfide and poly(3,4-ethylene two thiophene)on the foamed nickel to form MoS2-PEDOT@Ni F composites.MoS2@Ni F was prepared by using sodium molybdate and thiol acetic acid(TGA)as raw materials,and then further polymerized on EDOT with nickel foam to prepare MoS2-PEDOT@Ni F composite.Through preliminary exploration,the optimum conditions were determined as follows,sodium molybdate(0.048g),reaction temperature(200℃),reaction time(10h).MoS2@Ni F and MoS2-PEDOT@Ni F composites were characterized by SEM,EDS,XRD and XPS.The polarization curve,impedance and stability of MoS2@Ni,F PEDOT@Ni F and MoS2-PEDOT@Ni F composites were measured by electrochemical workstation.The results show that the composite material has a good catalytic capacity for hydrogen evolution.
