▎ 摘　　要

NOVELTY - Graphene oxide loaded core-shell structure cobalt nano particle composite material formed by uniformly distributed core-shell elemental cobalt nano particles on graphene oxide. USE - The graphene oxide loaded core-shell structure cobalt nano particle composite material is useful as alkaline electrolyzed water catalyst (claimed). ADVANTAGE - The material: improves catalytic performance, and is beneficial to catalytic hydrolysis of material in alkaline solution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene oxide loaded core-shell structure cobalt nano particle composite material comprising using graphene oxide as growth matrix, with the aid of surfactants, the two-dimensional nano-flaky cobalt glycerol self-assembled to form a flower-type structure attached to graphene oxide, forming a cobalt grapheme-surfactant/graphene oxide precursor, and reducing precursor at high temperature to form composite material.
