氮掺杂石墨烯/碳纳米管的制备及电容性能

his research aims to construct interface chemical bonding in different dimensions. Nitrogen-doped graphene / CNTs (N-G / CNTs) composites were grown on NiMgAl layered ternary metal hydroxide (LDHs) catalysts by one-step chemical vapor deposition (CVD). The effects of ion ratio in ternary metal catalyst, growth temperature, methane flowrate and growth timeon the capacitance performance of N-G / CNTs composites were investigated. It is confirmed that the graphene and CNTs in the N-G / CNTs composites are connected by covalent bonds, which promotes the construction of effective interfaces between different dimensions of materials. And nitrogen doping improves the wettability of N-G / CNTs composites, which is beneficial to the improvement of the electrochemical performance of the composites.
