摘要：
A novel and facile method was introduced for the preparation of carbon nanotubes/copper oxide (CNTs/CuOx) nanocomposites, which is based on in situ spontaneous redox reaction between Cu2+ and Sn2+. Sn2+ was adsorbed on the CNTs and displayed an important bridge role between the CNTs and Cu2+. The CNTs/CuOx nanocomposites can be obtained in situ by the spontaneous redox reaction between Cu2+ and Sn2+ at ambient atmosphere. The proposed CNTs/CuOx nanocomposites were investigated by transmission electron microscopy, energy dispersive X-ray microanalysis, X-ray diffraction, X-ray photoelectron spectroscopy and electrochemistry. Almost 5 nm CuOx nanoparticles were well distributed on the surface of CNTs and showed excellent electrochemical activity. The preliminary application of CNTs/CuOx nanocomposites toward electrocatalytic reduction of nitrate was also investigated. (C) 2012 Elsevier B.V. All rights reserved.
