Nanoporous carbons derived from metal-conjugated phosphoprotein/silica: Efficient electrocatalysts for oxygen reduction and hydrazine oxidation reactions

Efficient metal-free or nonprecious metal-based electrocatalysts are currently needed for many renewable energy conversion and storage devices. In this work, transition metal-conjugated casein-derived nanoporous heteroatom-doped carbon electrocatalysts for the oxygen reduction reaction (ORR) and the hydrazine oxidation reaction (HzOR) in fuel cells are reported. The electrocatalysts are synthesized from casein (or dairy phosphoprotein) that is...
