Exploring anomalously large H2 adsorption in microporous carbon

Hydrogen is considered one of the best alternative renewable fuels; however, its storage is still a challenge. Our recent work showed an extremely high H2 uptake of 13.8 mmol/g for fibrous micro-mesoporous carbon (FMMC) compared to the low porous Stober carbon (SC) obtained from templating of non-porous silica. We compared synthesized carbon materials with state-of-the-art carbon materials reported in the literature for H2 storage and FMMC showed high storage capacity at 1 bar comparable to the best-known carbons. In-situ neutron diffraction covering both small-angle and wide angles during D2 adsorption in the new generation microporous DFNC carbon with high surface area and porosity will provide an excellent opportunity to gain insight into the fundamental understanding of origin of extremely high H2 uptake.
