Hydrogenation/Dehydrogenation Catalysts for Hydrogen Storage Systems Based on Liquid Organic Carriers (A Review)

The state of the art in the field of studying catalysts for hydrogenation/dehydrogenation of organic substrates as potential components of modern hydrogen storage systems based on liquid organic hydrogen carriers is analyzed. The ways to reduce the content of noble metals or to replace them partially or fully by cheaper transition metals, prospects for using various supports, and possibilities of enhancing the activity, stability, and selectivity of the catalysts and of regenerating spent catalytic systems are discussed.
