A thermoregulated catalytic process has been elaborated using a ruthenium‐nanoparticle catalyst embedded into a supramolecular cyclodextrin‐based hydrogel matrix. Upon heating, the gel phase turned into a sol phase in which alkenes could be efficiently hydrogenated. Upon cooling, the reaction products and the metallic catalyst could be easily separated. The reusability of the system was clearly demonstrated.
