Chen, LuFink, CornelFei, ZhaofuDyson, Paul J.Laurenczy, Gabor2017-10-202017-10-202017-10-20201710.1039/C7GC01870Chttps://infoscience.epfl.ch/handle/20.500.14299/141507WOS:000415115600018Platinum nanoparticles (NPs) were synthesized in situ in the ionic liquid (IL) [Emim]NTf2 (1-ethyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide) as well as in mixtures of [Emim]NTf2 with a second IL, Lewis acid or Brønsted acid, but in the absence of additional stabilizers. The resulting NP/IL systems catalyze the hydrodeoxygenation of a phenol under mild conditions (60 °C, 1.0 MPa H2), achieving full substrate conversion and a high deoxygenation rate (over 95%) to cyclohexane and cyclohexene. The combination of [Emim]NTf2 and [Bmim]PF6 results in the best catalytic performance. Also the transform- ation of other substituted phenols and dimers such as catechol, guaiacol and diphenyl ether was studied in the Pt NP/[Emim]NTf2–[Bmim]PF6 system and in most cases afforded cyclohexane in good yield.hydrodeoxygenationPt nanoparticlesionic liquidscatalysistext::journal::journal article::research article
