摘要: Metal oxide films, including Ce2O3 and/or CeO2, Al2O3, La2O3, were deposited on the outer surfaces of carbon nanotubes (CNTs) through decomposition metal nitrate precursors in supercritical CO2 modified with ethanol. Transmission electron microscopy showed that CNTs could be coated layers nominally complete and uniform. The thickness coating readily tailored by tuning ratio initial mass to CNTs. as-prepared CeO2–CNT composites high sensitivity selectivity acetone basis chemiluminescence detection.
