This patent describes a new synthesis method for the large scale and low-cost production of size-selected nanoparticles with uniform 2D arrangement on a surface and nanowire patterned substrates with tunable width and interwire distance in a single preparation step. The nanoparticles prepared using our modified synthesis procedure exhibit an enhanced thermal stability and resistance against coarsening/sintering and desoreption at high temperature [at least 1060?C for Pt/TiO2(110)] thanks to the presence of a “polymeric glue” at the nanoparticle/support interface. Such thermally stable particles are can not only be stabilized on single crystal surfaces such as TiO2(110) but also on real-world catalytic supports such as nanocrystalline powders (anatase TiO2, CeO2, etc.). A second major advantage of our invention is the the possibility of using the strong nanoparticle/support interactions present in these low dimensional systems to create patterned surfaces at the nanoscale.
