Fig. 5.20 Thermoregulated Ru nanoparticle-catalyzed hydrogenation of alkenes. The ruthenium nanoparticles were embedded in the rotaxane-based gel
phase. When temperature has increased, the gel-sol transition occurred, and cyclodextrins could play the role of mass transfer and “bring” alkenes into the Ru
nanoparticle aqueous phase for their conversion into the corresponding alkanes. The catalytic system was recovered by the return of the temperature beyond
the transition phase temperature. (Adapted from Léger et al. 2012)
