▎ 摘 要
NOVELTY - Preparing high-stable three-dimensional graphene hollow sphere, comprises coating graphene oxide on surface of silicon dioxide sphere by electrostatic action using positively charged silicon dioxide sphere as a hard template, performing deoxidation and solidification by high temperature heat treatment, and removing the silicon dioxide sphere template to obtain high-stable three-dimensional graphene hollow spheres. USE - The high-stable three-dimensional graphene hollow sphere is useful as fuel cell catalyst support material (claimed), and as high-steady state electric catalyst carrier. ADVANTAGE - The method is simple and fast process, provides graphene hollow sphere having uniform size, complete shape, large specific surface area, high graphitization degree, excellent conductivity in electrochemical test, and excellent stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-stable three-dimensional graphene hollow sphere produced by the above method.
