The Ni-Mo-Co amorphous alloy was prepared by electrodeposition method, and the effects of different Ni / Co molar ratios on the properties of the alloy coating were studied at p H = 9.5 and t = 40 ~ Scanning electron microscopy, energy dispersive X-ray analyzer and X-ray diffraction were used to detect the morphology, elemental composition and crystalline structure of the Ni-Mo-Co alloy.The results show that the electrodeposited Ni-Mo-Co alloy Its appearance is silvery white, its surface is smooth and detailed, its structure is amorphous.The catalytic performance of Ni-Mo-Co alloy electrode in 1 mol / L NaOH solution was studied by linear sweep and AC impedance techniques.
