Abstract

Scanning transmission X-ray microscopy was used to chemically image RuO₂ nano-layer coated multi-walled carbon nanotubes (RuO₂/MWCNT) with a spatial resolution of 30 nm. X-Ray absorption near-edge structure spectroscopy of individual RuO₂/MWCNTs has been compared with that of MWCNTs and RuO₂ which confirms that RuO₂ interacts with MWCNTs through charge redistribution.
