Distorted Surface Ensembles in Platinum–Antimony for the Durable Catalytic Dehydrogenation of Methylcyclohexane [PDF]

JACS Au
Geometric and electronic effects are particularly pronounced when catalyzing small molecules, which require small active-metal ensembles. Researchers have been intensively focused on the alloy catalysis of small molecules. However, when large molecules are catalyzed, large active-metal ensembles are preferable to small active-metal ensembles.

Reactant-dependent volcano trends in Pt-catalyzed cycloalkane dehydrogenation: orbital hybridization-guided design of active sites [PDF]

Nature Communications
Catalyst design is often reaction-specific due to the lack of universal descriptors linking molecular structures to optimal active-site configurations. Here, we uncover a reactant-dependent volcano relationship in Pt-catalyzed dehydrogenation, governed ...

Zeolite Membrane‐Based Low‐Temperature Dehydrogenation of a Liquid Organic Hydrogen Carrier: A Key Step in the Development of a Hydrogen Economy [PDF]

Advanced Science
Methylcyclohexane (MCH) dehydrogenation is an equilibrium‐limited reaction that requires high temperatures (>300 °C) for complete conversion. However, high‐temperature operation can degrade catalytic activity and produce unwanted side products.
