Abstract:
Isopropanol dehydrogenation represents a pivotal step in the liquid organic hydrogen carrier cycle. Conventional thermocatalytic routes require high temperatures and entail substantial energy penalties, while low-temperature electrocatalytic processes suffer from sluggish reaction kinetics. Herein, we report an integrated thermo-electrocatalytic strategy within a high-temperature proton exchange membrane electrolyzer (HT-PEME), enabling highly efficient isopropanol dehydrogenation. A RuIr bimetallic catalyst was designed, wherein Ru sites effectively promote the cleavage of both O─H and C─H bonds in isopropanol, while the incorporation of Ir optimizes the adsorption behavior of reaction intermediates, thereby mitigating Ru site poisoning and significantly enhancing catalytic stability. At 200°C and 0.5 V, the integrated system delivers an exceptional anodic acetone production rate of 1336.36 mmol g-1 h-1, coupled with a cathodic H2 evolution rate of 1451.31 mmol g-1 h-1. This synergistic approach provides a robust and broadly applicable pathway for efficient H2 production.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
