Controlled growth of Ni nanocrystals on SrTiO₃ and their application in the catalytic synthesis of carbon nanotubes

2013

Truncated pyramid-shaped Ni nanocrystals were epitaxially grown on SrTiO₃(001) surfaces and characterised by scanning tunneling microscopy (STM). These nanocrystals were shown to be catalytically active for the synthesis of carbon nanotubes (CNTs). The narrow size distribution of the Ni nanocrystals results in a similar narrow distribution of CNT diameters.
