The concentration of the gas could be achieved by measuring the change of the conductivity. In the experiments, the gas sensor was prepared by spreading the water solution of carbon nanotubes between the interdigitated Au electrode, which was splashed on alumina. In this paper, three methods, such as mixing palladium and copper chloride, deoxidizing palladium and copper by chemical and electrochemical means, were used to doping palladium and copper in multi-wall carbon nanotubes.
