The growth of carbon nanotubes on large areas of silicon substrate using commercial iron oxide nanoparticles as a catalyst
A new approach to chemical vapour deposition (CVD) growth of carbon nanotubes (CNTs) using commercial magnetite nanoparticles, avoiding its in situ synthesis, is reported. Commercial magnetite nanoparticles were used as catalyst material to growth multiwalled carbon nanotubes by chemical vapour depo...
