PROCESS FOR THE DEPOSITION OF RUTHENIUM NANOSTRUCTURES OVER COBALT OXIDE INCORPORATED NITROGEN-DOPED CARBON

A method of forming ruthenium nanoparticles over cobalt oxide encapsulated nitrogen rich carbon nanotubes (Ru@CoOx/N-CNTs) from ZIF-12. The method includes mixing a first solution of cobalt nitrate hexahydrate, a benzimidazole solution, and N, N-dimethyl formamide. The first solution is transferred to a Teflon lined autoclave and heated at 150° C. The first solution is allowed to cool . The first solution is filtered and dried in an oven to produce a first composition. The method includes calcinating the first composition at 850° C. to obtain the cobalt oxide encapsulated nitrogen rich carbon nanotubes (CoOx/N-CNTs). The method includes coating the CoOx/N-CNTs with ruthenium to obtain Ru@CoOx/N-CNTs and dispersing the Ru@CoOx/N-CNTs in a Nafion+ isopropanol mixture. The electrochemical activity of Ru@CoOx/N-CNTs towards oxygen reduction reaction is measured.
