Laser Synthesis in Liquid Induced Lattice Distortion in PtFeSn/Activated Carbon for Enhanced Methylcyclohexane Dehydrogenation.

ABSTRACT: Methylcyclohexane (MCH) has emerged as one of the most promising liquid organic hydrogen carriers (LOHCs) for H₂ storage and long-distance transportation. Developing efficient, selective, and stable catalysts for MCH dehydrogenation is essential to make the process viable for practical applications. In this study, a platinum-iron-tin alloy supported on activated carbon (PtFeSn/AC) is reported, prepared via laser synthesis in liquid (LSL), exhibiting excellent dehydrogenation performance. The rapid crystallization and quenching inherent to the LSL process kinetically trap lattice distortions in the PtFeSn/AC catalyst due to atomic radius mismatches among Pt, Fe, and Sn. These distortions generate strain effects that create a local unsaturated coordination environment and downshif
