AbstractWe describe the rational design of a new versatile family of bifunctional catalytic materials based on the combination of supported metal nanoparticles (Pd, Rh, Ru) and the superacid, perfluorinated Aquivion® PFSA polymer. The heterogeneous catalysts were tested in the multi‐step valorisation of representative plant derivatives to high‐added‐value chemicals. Particularly, the conversion of (+)‐citronellal to (‐)‐menthol and levulinic acid to γ‐valerolactone was achieved in one pot and in one stage in the water phase and shows full selectivity at a high conversion level under mild reaction conditions. The results are discussed in terms of the catalyst micro‐structure.
