▎ 摘　　要

NOVELTY - Producing hydrogen storage carbon nanotube composites comprises: producing graphene oxide through improved chemical exfoliation of graphite materials; reducing the size of the produced graphene oxide through the chemical reduction of the metal particle size; preparing a precursor solution by mixing produced graphene oxide and carbon nano-composites in a mixture phase; and heat treating the mixture by in-situ hydrothermal reaction. USE - The method is useful for producing hydrogen storage carbon nanotube composites (claimed) that are used in semiconductor devices e.g. solar cells and fuel cells. ADVANTAGE - The method is capable of producing high efficient hydrogen storage carbon nanotube composites with high metal dispersion rate, improved hydrogen storage ability and excellent spillover effect.
