Abstract
A hierarchical graphene material composed of micropore
(∼0.8
nm), mesopore (∼4 nm), and macropore (>50 nm) and with a
specific
surface area up to 1305 m<sup>2</sup> g<sup>–1</sup> is fabricated
for physisorption hydrogen storage at atmospheric air pressure, showing
a capacity over 4.0 wt %, which is significantly higher than reported
graphene materials and all other kinds of carbon materials
