The realization of the Hydrogen Economy involves the development of efficient, safe, and lightweight H storage and delivery systems. Hydrogen molecular carriers (HMCs) have been proposed for this application, as they release and store H2 after catalyzed hydrogenation/dehydrogenation cycles, but efficient catalysts are still needed. In this work, we present a methodology for the development of nanocatalysts, using porphyrinic multivariate metal–organic frameworks (MTV-MOFs) as a precursor of supported nanoalloys/nanocomposites (M/ZrO2). MTV-MOFs with PCN-222 structure, containing atomically distributed mixtures of Pd, Pt, and Ni, yield dispersed nanoalloys after calcination, with a high metal loading. Both support and catalytically active phases are produced simultaneously during thermal treatment. The obtained materials demonstrate synergistic effects in the catalytic dehydrogenation of hydrogen molecular carriers, namely, ammonia borane (AB), 2-methylpiperidine (2MP), and a liquid mixture of 2MP and DHC (dodecahydro-1H-carbazole).
