AbstractNi-Co-Al alloys with different Co contents were prepared by vacuum smelting and rapid solidification. XRD, SEM, TEM and N-2 adsorption-desorption were used on the structure characterization of nanoporous Ni-Co, and the hydrogen evolution performance of nanoporous Ni-Co/GCE electrode was tested by linear sweep voltammetry (LSV) and ac impedance(IMP). The results showed that there were smaller pores (5 similar to 10 nm) on the surface of the nanoporous Ni-Co alloy skeleton, and the catalytic performance of hydrogen evolution was better when the Co content was 40%similar to 60% (w/w). Among them, the pores of Ni2.5Co2.5 and Ni3Co2 are almost uniform, and they have smaller mesoporous pores than others, which is beneficial to the infiltration of electrolyte and increase the surface area of the electrode.Therefore, Ni2.5Co2.5/GCE and Ni3Co2/GCE have high hydrogen evolution performance. When the current density was -0.005 A . cm(-2), the hydrogen evolution potential of the two electrodes were almost the same as 380 mV.
