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

Through molecular design of a solid precursor, we engineer a novel nanocomposite composed of bimetallic (Ni-Fe) phosphide nano-particles 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.
