Abstract

The electronic structures of carbon nanotube/RuO₂ core/shell nanocomposite (RuO₂ thin layer coated multiwalled carbon nanotubes (MWNTs)) have been studied by X-ray absorption near-edge structures (XANES) at C K-edge, O K-edge, and Ru M_5,4- and L₃-edges. The variation in white-line features of the XANES at these edges supports strongly that RuO₂ interacts with MWNTs through Ru - O - C bonding, which also results in charge redistribution between C 2p-derived states in MWNT and the conduction band in RuO₂. Such chemical bonding is necessary to immobilize RuO₂ on MWNT and ensures good conductivity of MWNT/ RuO₂ core/shell nanocomposite.
