Abstract:
We evaluate the hydrogen adsorption behavior of the pristine single-layer graphene sheets in a powder form, which was performed at cryogenic and room temperatures. Only 0.4 wt.% and<0 .2 wt.% hydrogen uptake was obtained at 77 k under 100 kpa and room temperature under 6 mpa, respectively, for the pristine graphene sample with a bet specific surface area of 156 m2 g−1. structure/property investigations suggest that the low specific surface area and weak binding to hydrogen should be responsible for the small gravimetric uptake of pristine graphene sample.
