摘要(Abstract)：

采用一步水热合成的方法在钼网(MF)上原位构筑MoSe_2/CoSe_2异质结构电催化剂。采用X射线衍射仪(XRD)、扫描电镜(SEM)、透射电镜(TEM)和X光电子能谱仪(XPS)等对MoSe_2/CoSe_2异质结构的物相和形貌进行了表征，并在1 mol/L KOH电解液中对该电催化剂的析氢反应(HER)性能进行了测试。结果表明：MoSe_2/CoSe_2@MF-2为枝状阵列异质结构，在电流密度为10 mA/cm~2下，其过电势为172.3 mV,Tafel斜率为45.8 mV/dec,表现出良好的HER性能和结构稳定性。该异质结构电催化剂的成功构筑，为后续硒化物异质结及其在电催化中的应用提供了良好的思路和研究基础。
