Electrochemical Water Splitting

Generation of hydrogen fuel through electrochemical water splitting is the most eco-friendly approach. Herein we have developed a core-shell material consisting NiCo-LDH deposited on Cu wires grown on Cu mesh which surpasses the activity of 40% Pt/C. This particuar catalyst requires 15 and 27 mV overpotential for hydrogen evolution in alkaline and acidic medium, respectively, along with durability at high current density and flexibility. Density of state calculation explains the reason of better activity of Cu wire than Cu mesh.
