  "abstract": "In hydrogen storage technologies with liquid organic hydrogen carriers, the development of efficient catalysts for methylcyclohexane dehydrogenation is highly important. In this study, we developed atomically precise platinum nanocluster catalysts supported on Al2O3 (Ptx/Al2O3; x = 17, ~51). Comprehensive characterization demonstrated that the catalysts remained highly monodisperse and of uniform particle size (0.86 or 1.15 nm), and maintained a cationic electronic state (Ptδ+) even after thermal treatment. Remarkably, the Pt17/Al2O3 and Pt~51/Al2O3 catalysts exhibited a mass activity up to 7.9 and 8.2 times higher than that of conventional nanoparticle catalysts. Furthermore, by effectively suppressing undesirable cracking pathways at a low operating temperature of 250 °C, the catalyst achieved both high selectivity (byproduct yield < 3%; below the detection limit) and durability. These findings pave the way for practical guidelines in advanced catalyst design.",
