Abstract
It is demonstrated that surface oxygen functional groups are able to enhance hydrogen storage capacities by facilitating hydrogen spillover in metal-doped activated carbon sample. By facile treatment of activated carbon with NaOH and H2O2, surface oxygen groups, such as carbonyl (-C=O) and hydroxyl (-OH) were formed on the surface of activated carbon. The changes in structure, morphology, and porosity of the oxidized carbon materials were characterized by XRD and nitrogen adsorption experiments. The type and concentration of surface oxygen groups were analyzed by TPD, FTIR, XPS. The role of surface oxygen functional groups and enhanced microporosity in hydrogen spillover is explored in the paper.
