Metal oxide films, including Ce 2 O 3 and/or CeO 2 , Al 2 O 3 , La 2 O 3 , were deposited on the outer surfaces of carbon nanotubes (CNTs) through the decomposition of metal nitrate precursors in supercritical CO 2 modified with ethanol. Transmission electron microscopy showed that CNTs could be coated with metal oxide layers that were...
Titanium dioxide (anatase, TiO 2 ) nanoparticles have been successfully deposited onto multi-walled carbon nanotubes (MWCNTs) via hydrolysis of titanium isopropoxide in supercritical ethanol. The as-prepared composites were characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. It was demonstrated that the MWCNTs were decorated with well-dispersed...
PtRu nanoparticles were decorated on multi-walled carbon nanotubes (MWCNTs) using H 2 PtCl 6 and RuCl 3 as precursors with the aid of supercritical CO 2 , and the resulting composites were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy. TEM observation showed that nanoparticles of size about 5nm...
