Methods for determining particle size of metal nanocatalyst for growing carbon nanotubes |
摘要 |
Methods and processes for determining the particle size distribution of metal catalysts are provides. Superconducting Quantum Interference Device (SQUID) magnetometer is used to evaluate the magnetic catalyst particle sizes dispersed in the support material. Dependence on variation of the metal/support material ratio, which defines the metal particle sizes, the catalyst can show paramagnetic, superparamagnetic, and ferromagnetic behaviors.
