In this work, unique amphiphilic magnetic hybrid carbon nanotubes that contain on the same nanotube two different sections: a hydrophobic undoped part connected to a hydrophilic N-doped segment are synthesized and used as supports for palladium catalysts. These new Pd-supported catalysts have been used in the alcohol oxidation reaction using molecular oxygen in the liquid phase. The oxidation of 2-heptanol produces selectively the ketone, the oxidation of benzyl alcohol is very selective towards the aldehyde, and ethanol oxidation produces selectively acetic acid.
