| Abstract: | A series of carbon nanotube supported cobalt nitrides are synthesized through impregnation methods and temperature-programmed reaction.The surface composition and reaction performance are studied by means of ammonia decomposition,XRD,BET,TG-DSC,H_2-TPR techniques.The results show that CoN_x/CNTs exhibited high activity for ammonia decomposition,the conversion of ammonia is up to 66.46%at 500℃. |
