Application of carbon materials in catalytic systems for the hydrogenation-dehydrogenation of liquid organic hydrogen carriers

Carbon materials with different textural characteristics (active carbon, carbon nanotubes, and Sibunite) for the purposes of hydrogen generation and storage and its evolution in processes using liquid organic hydrogen carriers are compared. A combination of structural and physicochemical characteristics (surface functionalization, controlled metal-carbon interaction, and relative chemical inertness) provides advantages of the modern carbon materials over oxides as catalyst carriers, since they allow the accumulation (hydrogenation) and evolution (dehydrogenation) of hydrogen to occur without cracking product formation. The prospects of the Sibunite-based Pt catalysts in these reactions are shown.
