Advanced oxygen evolution catalysis by bimetallic Ni–Fe phosphide nanoparticles encapsulated in nitrogen, phosphorus, and sulphur tri-doped porous carbon

Abstract

Through molecular design of a solid precursor, we engineer a novel nanocomposite composed of bimetallic (Ni–Fe) phosphide nanoparticles encapsulated in a N,P,S-tri-doped porous carbon matrix. With tailorable compositional and architectural features, the resultant nanocomposite presents remarkable performance in electrochemical water oxidation.
