Amorphous Zr64Ni36 and Zr48Ni27Al25 alloys have been characterized by physico-chemical structural and electrochemical techniques in view of their possible application as electrocatalytic materials for hydrogen evolution reaction. Phase transformations of the amorphous materials have been observed by X-ray diffraction and differential scanning calorimetry. the overall experimental data indicate that interesting electrocatalytic performances are obtained with samples chemically pre-treated in HF solution. In the case of Zr48Ni27Al25 a leaching pre-treatment was also tried with the purpose of obtaining a highly porous structure as a consequence of Al elimination.
