Sustainable and Energy-Saving Hydrogen Production via Binder-free and In-situ Electrodeposited Ni-Mn-S Nanowires on Ni-Cu 3-D Substrate

A bi-functional electrocatalyst based on Ni–Mn–S nanowires@Ni–Cu micro–nano dendrites was designed for the HER and UOR, which demonstrated favorable catalytic activity and stability for energy-saving hydrogen production.
