(a) Substrate after dip-coating in catalyst solution. (b) After calcination at 200°C iron nanoparticles are formed. (c) The iron particles agglomerate to form bundles of different diameters. (d) The agglomerated iron nanoparticles emerge into GNR in the presence of argon as carrier gas and ethanol as the carbon feedstock at high temperature. The GNRs emerge into different widths due to nonuniform diameters of the iron nanoparticles.
