Abstract
Liquid organic hydrogen carriers (LOHCs) store hydrogen gas (H₂) safely and reversibly through covalent bonding via hydrogenation and dehydrogenation reactions, enabling large-scale H₂ transportation using gasoline infrastructure. Among them, monohydric alcohols/monoketones can release H₂ under mild conditions (<200 °C) due to their low dehydrogenation enthalpies. In this work, we demonstrate a new class of LOHCs based on polyhydric alcohols/polyketones, which can store H₂ densely while maintaining the low dehydrogenation enthalpies of monohydric alcohols. In addition, ….
