Abstract :
Multi-wall carbon nanotubes decorated with different metal or metal oxide nanoparticles were used for gas sensing applications in a chemical resistor configuration. In this configuration, multi-wall carbon nanotubes serve as a conductive channel (for electrical signal acquisition), a heating element (for local heating of attached nanoparticles), and a substrate for nanoparticles growth or deposition, whereas the role of nanoparticles is to provide selective sensitivity to specific gases.
