Abstract

Abstract: Ir/CNTs and Ir/C catalysts were prepared with multi-wall carbon nanotubes(CNTs) and Vulcan XC-72 activated carbon(XC-72) as supporting carbon material, respectively. X-ray diffraction(XRD) measurements show the graphitization degree of CNTs is higher than that of XC-72, which indicates that CNTs possesses higher electron conductivity than that of XC-72. In comparison to Ir/C catalyst, the Ir/CNTs catalyst has higher oxidation current, lower onset oxidation potential and better stability for ammonia electro-oxidation. During the electrochemical detection of ammonia, the Ir/CNTs catalyst modified electrode possesses a lower detection-limit, a wider linear range of detection and a higher sensitivity compared to Ir/C catalyst. Thus, CNTs may be an ideal catalyst supporting material for the practical application of amperometric NH3 sensor.
