Abstract

The aim of this work is to obtain new materials for electrocatalysis based on nanostructured copper and zirconium alloys. New nano phase-separated material Cu#ZrO2 deducted from conventional Cu51Zr14 alloy precursor was developed. The materials’ characteristics were determined using FE-SEM, STEM, XRD and electrochemical methods. The optimal conditions for the nano separation in alloy system have been established. Under conditions of heat treatment evolution of phase separation occurs through the exchange events between atoms and inward-outward migration of cations and anions. The electrochemical and BET surface area was determined. Based on the processing of the electrochemical data Cu#ZrO2 demonstrates promising potential for electrocatalytic activity.
