Effect of Pt nanoparticle decoration on the H2 storage performance of plasma-derived nanoporous graphene

Abstract A nanoporous and large surface area (∼800 m2/g) graphene-based material was produced by plasma treatment of natural flake graphite and was subsequently surface decorated with platinum (Pt) nano-sized particles via thermal reduction of a Pt precursor (chloroplatinic acid). The carbon-metal nanocomposite showed a ∼2 wt.% loading of well-dispersed Pt nanoparticles (
