Abstract

Abstract: Instead Vulcan XC-72 carbon(XC), grapheme(G) was used as the support to prepare the Ir/G catalyst. The electrochemical measurement indicted that the electrocatalytic performance of the Ir/G catalyst for the ammonia oxidation was better than that of the Ir/XC catalyst. XRD and TEM measurements indicated that the average sizes of Ir particles in Ir/G and Ir/XC catalysts were similar. The measurement of the Raman spectroscopy illustrates the graphitization extent of G is higher than that of XC. Thus, the conductivity of G is higher than that of XC. Therefore, the electrocatalytic performance of the Ir/G catalyst is better than that of the Ir/XC catalyst can be attributed to the high conductivity due to the high graphitization extent of G. The results show that there is the good linear relationship between the current density of the ammonia oxidation at the Ir/G catalyst electrode and the concentration of ammonia. The related coefficient(R) is 0.99557. Thus, Ir/G catalyst electrode can be used as the working electrode in the current type of electrochemical ammonia sensor.
