Abstract

An ordered mesoporous carbon of CMK-3 type was prepared and modified by metal doping with Pd nanoparticles. The hydrogen sorption performance of the pristine and composite materials was studied at different temperature and pressure conditions in order to provide insight into the underlying storage mechanism. It was shown that metal doping can lead to enhanced hydrogen storage at 298 K as a result of a weak chemisorption process initiated by the so-called “spillover” effect.
