Cover Feature: Bridging Dehydrogenation and Hydrogenation in Heterogeneous Catalysis: A Demonstration of a Unified Catalytic Approach (Chem. Eur. J. 47/2024)

A proof of concept for reversible hydrogen storage focuses on the cyclooctane–cyclooctene system. A hybrid catalyst comprising a unique combination of an organometallic pincer complex, [Ir(C2H4){OP(tBu)2-C6H2-2,6-[OP(tBu)2]2}] (depicted as crabs) and Pd−Ru nanostructures (depicted as spheres) immobilized on γ-alumina support (depicted as snowflakes) brings about dehydrogenation and hydrogenation in a tandem fashion. The hydrogen released holds promise as a viable automotive fuel source. The study provides valuable insights for the design and development of tandem catalysts for reversible hydrogen storage in liquid organic hydrogen carriers.
