Résumé

Sucrose-based microporous carbons were prepared for hydrogen storage. Carbon precursors were generated by ultrasonic and heat treatment of a solution of sucrose in sulfuric acid. Chemical activation was performed with KOH at various temperatures, leading to enhanced specific surface area and micropore volume. The structural properties and the morphology were evaluated XRD and SEM, respectively. The textural properties were determined from N₂/77K adsorption-desorption isotherms using the BET method and HK equation. The hydrogen storage capacity was influenced by the activation temperature, and the optimal hydrogen storage capacity of 2.5wt.% at 77K and 1bar.
