A known method for producing porous graphitized carbon material covered with metal nanoparticles involves infiltrating a porous template framework of inorganic material with a carbon precursor. After thermal treatment of the precursor, the template is removed and the particulate porous carbon material is covered with a catalytically active substance. According to the invention, in order to keep the proportion of the noble metal loading at a low level, the thermal treatment of the precursor first involves carbonization, and the material is not graphitized into graphitized, particulate, porous carbon material until the template has been removed. The graphitized carbon material has a hierarchical pore structure with a pore volume of at least 0.5 cm/g and at least 75% of the pore volume is apportioned to macropores with, size 100 to 5000 nm. Before covering with catalytically active substance, the carbon material is subjected to an activation treatment in an oxidizing atmosphere.
