The methylcyclohexane (MCH)-toluene (TOL) system, one of the hydrogen carriers, has attracted much attention due to its easy handling. Conventional MCH dehydrogenation catalysts often use Pt nanoparticles, but they waste a large amount of internal Pt. In this presentation, we report that a catalyst consisting of Pt single atom on Cu and Fe base metal alloys is a possible solution to the above problem. The TOF of the Pt single atom alloy catalyst (Pt₁-CuFe-r-TiO₂) at 350°C was 15 times higher than the maximum value reported previously.
