NixCo3−xO4 Nanowire Arrays for Electrocatalytic Oxygen Evolution

Authors


Abstract

original image

NixCo3−xO4 nanowire arrays are grown on a Ti foil for efficient oxygen evolution reactions. Ni-doped nanowire arrays have higher electrocatalytic activity than pure Co3O4. The success of the nanowire electrodes results from their high surface areas and direct electron contact to the conductive substrate.
