摘要：

An overview is given of the development of nanoporous graphene monolith as storage materials for molecular hydrogen for next-generation low-pressure tanks. Compacting activated carbon powder into monolith is an efficient space-filling technique to increase the volumetric storage capacity. Monolith has been synthesized with a packing density of 0.7 g/cm(3) using MSC30 and Polyvinyl alcohol (PVA). The presence of the pyrolyzed binder decreased the excess adsorption by 34 % and the gravimetric storage capacity by 48%. Despite the decrease in excess adsorption, the volumetric storage capacity increased by 30% due the high packing configuration of monolith. (C) 2017 Elsevier Ltd. All rights reserved.
