Abstract: Experimental procedures have been developed to prepare carbon nanotubes (CNTs) decorated by metal oxides nanoparticles for gas sensing applications. For decoration of carbon nanotubes with Sn and Cu oxides, the concentration of precursors and time of sonication were found to be crucial parameters, to control the size and density of nanoparticles on the nanotubes surface. In the case of CNTs decorated with Ti oxides, the pH value of the solution was found to play a key role in the final size of the nanoparticles. The material decorated with SnO2 was tested with H2S and changes in the conductivity showed the potential of this material for gas sensing application. © The Electrochemical Society.
