摘要

以钼酸铵为钼源、硫脲为硫源,使用核桃壳活性炭通过水热法成功制备二硫化钼(MoS₂)/核桃壳活性炭复合纳米材料。研究了MoS₂含量对复合纳米材料形貌、尺寸及电化学性能的影响,通过X射线粉末衍射仪、冷场发射扫描电子显微镜、比表面积及孔隙度分析仪、线性扫描伏安法对复合纳米材料的结构、形貌、电化学性能进行分析和表征。结果表明,MoS₂质量分数为80%的MoS₂/核桃壳活性炭复合纳米材料的电催化析氢反应活性最好。

Abstract

The molybdenum disulfide(MoS₂)/walnut-peel-activated carbon nanocomposites were synthesized by a hydrothermal method using ammonium molybdate as the molybdenum source and thiourea as sulfur source.The effects of different quality of MoS₂ loading on the morphology,size and electrochemical properties were studied.Scanning electron microscopy (SEM),X-ray diffraction (XRD) and linear cyclic voltammetry (LSV) were applied to characterize the morphology,structure and electrochemical properties of synthesized materials.The results showed that 80% (weight ratio) MoS₂/walnut-shell-activated carbon nanocomposites had the best performance of electrochemical hydrogen evolution reaction.
