Abstract
The current study presents for the first time the preparation of a NiAl(68％(mass)Ni)intermetallic compound through the induction heating technique as a cathode for alkaline water electrolysis.The high-purity target was confirmed by X-ray diffraction and scanning electron microscopy combined with energy dispersive X-ray analysis.The chemical activation of Al from the NiAl electrode was achieved in a 25％NaOH solution at 353 K for 72 h.The performance and stability tests in a 1 mol·L-1 KOH solution at 298 K demonstrated that the enhancement of the hydrogen evolution reaction was 13 times higher in the activated NiAl electrode than in the non-activated NiAl electrode.In addition,the electrochemical tests showed that the activated NiAl electrode exhibited the best hydrogen evolution reaction performance.Based on the findings,it is believed that the induction heating technique is a promising route for pre-paring a highly active and cost-effective NiAl electrode for green hydrogen production.
