Abstract: The present invention is directed to a composite material of a carbonaceous substance comprising a doped catalytic compound obtained by a sol-gel method. In one embodiment, the method comprises mixing a hydrolyzed solution comprising a precursor of a catalytic material with a carbonaceous material to obtain a sol. The sol is afterwards incubated while at the same time it is mixed. After incubation the sol is condensated to form a gel.
