Abstract:
1. A method for activating a catalyst composition for catalyzing a reaction selected from the group consisting of oxidation, hydrogenation, dehydrogenation, oxidative-hydrogenation, and oxidative-dehydrogenation, which catalyst composition is comprised of graphitic nanostructures which nanostructures are comprised of a plurality of graphite platelets aligned parallel, perpendicular, or at an angle to the longitudinal axis of the nanostructure and which graphitic nanostructures wherein at least about 50% of its edge sites are exposed, which method for activating comprises treating said nanostructures with a mixture of CO 2 and H 2 at an effective temperature for period of time from about 0.5 hours to about 70 hours.
