Activating FeMoO4 nanosheet arrays by partial nickel substitution for efficient electrocatalytic seawater oxidation†
Abstract
Nickel-substituted FeMoO4 nanosheet arrays in situ assembled on a nickel foam skeleton are fabricated by a spontaneous redox reaction. Due to the synergistic effect of the increase of exposed active sites and improvement of electron transfer, the targeted catalyst exhibits excellent electrocatalytic performance for seawater oxidation.
