Abstract:
1. A method for synthesizing carbon nanotubes comprising: making a first liquid phase metal salt powder catalyst solution of a first volume; making a second, different liquid phase metal salt powder catalyst solution of a second volume; making a C ultrasonicating the first metal salt catalyst, the second metal catalyst, and the C depositing predetermined volumes of droplets of the first dispersed solution, the second dispersed solution, and the carbon source dispersed solution onto a substrate; drying the first dispersed solution, the second dispersed solution, and the carbon source dispersed solution on the substrate in an air environment for a predetermined time to form a carbon and catalyst mixture; and heating the carbon and catalyst mixture in the air environment for a predetermined temperature and time resulting in the growth of one or more carbon nanotubes.
