Dynamics of Gold Nanoparticles on Carbon Nanostructures Driven by van der Waals and Electrostatic Interactions

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...

Zusammenfassung: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 graph­ene surface.
