This work addresses the bio-waste valorization approach for the development of a novel carbonaceous nanomaterial to be used in the adsorption of hydrogen as an alternative in the use of green hydrogen. In this research, activated carbons were synthesized using peanut shells and different synthesis conditions. The activated carbon with the best structure and texture, the adsorption of hydrogen and the effects on their microporosity were studied.The best support obtained presents a BET area of 1350 m2 / g. Said material significantly improved H2 storage behavior compared to CMK-3 type nanostructured carbon (2.8% by weight at -196,15 oC and 10 bar). The synthesized material shows promise in absorbing hydrogen by weak binding forces (physisorption).
