三维石墨烯/碳纳米管复合材料的制备及超电容性能研究
摘要
Abstract
The purpose of this study is to explore the production methods and supercapacitance properties of three-dimensional graphene/carbon nanotube composites.Ni-Mg-Al ternary metal oxides(TMO)were prepared by equilibrium deposition,and carbon nanotubes(CNTs)were successfully prepared by one-step chemical vapor deposition(CVD)with CH4 as carbon source and Ar as protective gas.Carbon nanotubes(CNTs)were successfully prepared by in-situ reduction of Ni,and graphene(GR)was formed in the metal oxides of Mg and Al.Finally,the mixture of CNTs/three-dimensional graphene(3DGR)was successfully produced by hydrothermal treatment to remove TMO effectively.At the same time,by adjusting the molar ratio of Ni,Mg and Al metal ions,growth temperature and growth time,and with the help of the structure and capacitance characteristics of CNTs/3DGR composites,the growth kinetic differences of CNTs and GR were properly managed and improved.Through research,it is found that the electron transmission path of CNTs composites is the joint action of CNTs and GR,which has a positive effect on significantly improving its electrical conductivity and further enhancing its capacitance properties.关键词
