▎ 摘　　要

NOVELTY - Palladium-reduced graphene composite comprises first palladium nanoparticles, second palladium nanoparticles spaced apart from the first palladium nanoparticles, a first reduced graphene for surrounding the upper portion of the first and second palladium nanoparticles, and a second reduced graphene surrounding the lower portion of the first and second palladium nanoparticles. USE - The palladium-reduced graphene composite is useful in storing and transporting hydrogen energy. ADVANTAGE - The palladium reduced graphene composite: can be manufactured with fast absorption rate and high stability without storage loss; and has simplified process and strong compressive stress.
