Tungsten carbide(WC)/carbon nanotube(CNT)nanocomposite was prepared by surface decoration and in situ reduction techniques.The structure,morphology and thermal stability of the sample were characterized by XRD,SEM and TG-DTA methods.The results showed that the sample which was composed of WC uniformly supported on the surface of CNTs exhibited high thermal stability in air.The electrocatalytical activity and electrochemical stability of the WC/CNT nanocomposite for the electroreduction of nitrobenzene were investigated by cyclic voltammetry.The results showed that WC/CNT nanocomposite exhibited better catalytic activity for the electroreduction of nitrobenzene than separate WC nanoparticles and CNTs,and it also had good electrochemical stability during the process of electroreduction of nitrobenzene in acid solution.
