Phytic acid assisted ultra-fast<i>in situ</i>construction of Ni foam-supported amorphous Ni–Fe phytates to enhance catalytic performance for the oxygen evolution reaction

Abstract

A phytic acid-induced etching and complexation growth strategy is used to fastly prepare the amorphous bimetallic Ni–Fe phytate with a cross-linked structure on nickel foam, which shows efficient catalytic activity and robust stability for OER.
