摘 要: 采用等体积浸渍法结合程序升温还原技术合成了一系列CoNx/CNTs催化剂,通过XRD、BET、TG-DSC、TPR等手段,结合氨分解反应,研究了它们的表面性质和反应性能,结果表明,CoNx/CNTs催化剂对氨分解反应具有良好的催化活性,在500℃时氨转化率可达到66.46%。 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, H2-TPR techniques. The results show that CoNx/CNTs exhibited high activity for ammonia decomposition, the conversion of ammonia is up to 66.46% at 500℃.
