A process for preparing a catalyst, wherein said process comprises: (i) preparing a mixture of one or more aromatic alcohol monomers and / or non-aromatic monomers, solvent, polymerization catalyst, crosslinking agent, suspension stabilizing agent and one or more plus metal salts, under conditions sufficient to produce polymeric beads doped with one or more metals or salts thereof; (ii) charring, activating and then reducing the polymeric beads produced in step (i) to produce porous carbon beads doped with metallic nanoparticles; (iii) subjecting the metal nanoparticle doped porous carbon beads produced in step (ii) to chemical vapor deposition in the presence of a carbon source to produce metal nanoparticle doped porous carbon beads comprising carbon nanofibers; and (iv) doping the porous carbon beads doped with metal nanoparticles comprising carbon nanofibers produced in step (iii) with an oxidant by mixing the beads with an aqueous solution comprising the oxidant at a temperature in the range of 40 at 60 ° C for a period of 4 to 12 hours, where after mixing, the catalyst is filtered and dried. |
