In this work, we report the synthesis of a hybrid material, consisting of Cu nanoparticles (Cu-NPs) anchored on the surface of carbon nanotubes (CNTs), which is able to increase the catalytic behavior when compared to bare CuNPs. This enhanced activity was evalu-ated by the electrophoretic separation of three carbohydrates: sucrose, glucose and fruc-tose. CNTs were first synthesized in the presence of minute amounts of oxygen, oxidized using H 2 O 2 -UV radiation and then decorated with Cu-NPs. The resulting hybrid structure was confirmed and characterized by X-ray photoelectron spectroscopy, transmission elec-tron microscopy, high resolution transmission electron energydispersive X-ray spectros-copy, titration, thermogravimetric analysis, elemental analysis and Raman spectroscopy.
