Electronic Structure of CuI@SWCNT Nanocomposite Studied by X-Ray Absorption Spectroscopy

Abstract

The present study is aimed to characterize the possible chemical interaction between CuI and SWCNTs in CuI@SWCNT and electronic structure of the latter with X-ray absorption spectroscopy. Comparative analysis of C1s and Cu2p absorption spectra for CuI@SWCNT and reference samples in the framework of the quasi-molecular approach shows that encapsulation of CuI into SWCNTs is accompanied by the changes in electronic structure of CuI due to the ones in atomic structure of CuI in the composite and the chemical interaction between the filler and carbon nanotubes.
