▎ 摘  要

NOVELTY - Preparing monovalent gold nano particle/three dimensional graphene/nickel foam composite structure comprises using chloroauric acid as gold source and sodium borohydride as reduction agent, and using oxidation-reduction method to obtain monovalent gold nano particle, then using chemical vapor deposition (CVD) method for preparing three dimensional graphene/nickel foam composite structure, and finally using electrophoresis deposition method to obtain the composite structure. USE - The composite structure is useful in electrochemical sensor and environmental pollution treatment. ADVANTAGE - The method: is simple (claimed) and easy to operate; has stable process and low cost; produces the gold nano particles, which are uniformly distributed; and produces the three dimensional network structure with continuous hole, high activity and conductivity.
