▎ 摘 要
NOVELTY - Transition metal alloy carbon composite material comprises carbon material and alloy particles dispersed on surface of the carbon material; the alloy particles includes nickel (Ni) and nickel-cobalt (NiCo) nano-alloy particles coated on the surface of nickel. USE - The composite material is useful in field of electrocatalytic oxygen evolution reaction (OER), oxygen reduction reaction (ORR) and metal-air battery (preferably zinc-air battery). ADVANTAGE - The composite material: has uniform particle size distribution, special core-shell structure, good bifunctional catalytic effect, and has very high catalytic stability in oxygen evolution reaction or oxygen reduction reaction; and contains large amount of defect and electro-catalysis needed active site. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the the transition metal alloy carbon composite material comprising mixing the cobalt source, nickel source and oleylamine to obtain a mixture; heating and reacting the carbon material and above mixture to obtain transition metal alloy carbon composite material.
