摘要
通过喷雾干燥技术和热处理工艺制备了碳纳米管/石墨烯球-纳米镍(CNTs/GR-Ni)复合材料,并对其吸附性能和催化性能进行了研究。结果表明:利用喷雾干燥技术并经适当热处理成功制备了碳纳米管/石墨烯负载纳米镍的复合材料,纳米镍颗粒均匀地分布在碳纳米管/石墨烯微米球的表面;碳纳米管/石墨烯-纳米镍具有优异的吸附性能和磁性分离性能;与单质镍相比,碳纳米管/石墨烯球-纳米镍具有优异的催化性能,将高氯酸铵的高温分解温度降低了135℃。
The composite of carbon nanotubes/graphene spheres-nano Ni （CNTs/GR-Ni） was synthesized by spray drying technology and heat treatment process. The adsorption property and catalytic performance were researched. The results showed that the composite of carbon nanotubes/graphene spheres loaded nano-Ni was successfully fabricated by spray drying technology and heat treatment process and Ni nanoparticles were distributed uniformly on the surface of carbon nanotubes/graphene microspheres. CNTs/GR-Ni had excellent adsorption property and magnetic separation property. Compared with the element Ni, CNTs/GR-Ni had the excellent catalytic performance and it made the temperature of high temperature decomposition of ammonium perehlorate decrease by 135℃.
