Abstract

Transmission electron microscopy studies on the assembly and growth of gold nanoparticles on carbon nanotubes supported on few-layer graphene and amorphous carbon reveal a competition between van der Waals forces and electrostatic interactions, enabling controlled positioning and sizing of adsorbed nanoparticles at the nanochannels formed between the carbon nanotube and the few-layer graph-ene surface.

摘要

透射电子显微镜研究表明，在少层石墨烯和非晶碳负载的碳纳米管上组装和生长金纳米粒子时，范德华力和静电相互作用之间存在竞争，这使得在碳纳米管和少层石墨烯表面之间形成的纳米通道中吸附的纳米粒子能够被控制定位和尺寸化。
