摘　　要：在电解水析氢析氧过程中,反应生成的气体易粘附粉末状电极的表面,形成严重的"气泡屏蔽效应"。因此制备出电催化性能优异且超疏气纳米结构电解水电极具有重大意义。通过选取具有亲水性的本征材料,利用恒电位沉积与高温缓慢氧化制备超疏气的Co-Mo-Cu-O微纳米电极,并研究了其作为电解水催化剂的析氢析氧活性以及超疏气性能。In the process of electrolyzing water to separate hydrogen and oxygen, the gas generated by the reaction easily adheres to the surface of the powdery electrode, forming a serious "bubble shielding effect". Therefore, it is of great significance to prepare an electro-catalytic performance electrode and an superaerophobic nanostructure electrolyzed water electrode. In this paper, the superaerophobic Co-Mo-Cu-O micro-nanoelectrode was prepared by potentiostatic deposition and high temperature slow oxidation by selecting the intrinsic material with hydrophilicity, and the hydrogen evolution and oxygen evolution activity of the electrolyzed water catalyst and degassing performance were studied.
