We describe a catalytic system composed of rhodium nanoparticles immobilized in a Lewis acidicionicliquid. The combined system catalyzes the hydrogenation of quinolines, pyridines, benzofurans, and furan to access the corresponding heterocycles, important molecules present in fine chemicals, agrochemicals, and pharmaceuticals. The catalyst is highly selective, acting only on the heteroaromatic ring

Pyrolysis of Co-DABCO-citric acid template on silica resulted in stable and reusable Co/Co3O4 core–shell nanostructured catalyst which allows for the selective hydrogenation of benzofurans as well as indoles and benzothiophenes.
