Abstract: A method for producing carbon particles having a core/shell structure includes infiltrating a pore-containing template material with a first precursor for carbon of a first variety, carbonizing the first precursor to form a deposit of the carbon of the first variety, infiltrating the remaining pore space with a second precursor for carbon of a second variety to form a second deposit of the carbon of the second variety which has a second porosity lower than the first porosity, and removing the template material to form the carbon particles. The template material is provided as template particles and the first precursor is provided as precursor particles of meltable and polymerizable material. The infiltration occurs in the molten phase so that the first precursor is foamed before or during the carbonization to form a pore-containing carbon foam.

Before covering with catalytically active substance, the carbon material is subjected to an activation treatment in an oxidizing atmosphere.
