Fabrication of periodic nanoparticle arrays using nanosphere lithography technique and thin film gold as electrically enhanced catalysts

Nanosphere lithography (NSL) is a versatile, facile and parallel nanofabrication technique, especially in fabrication of periodic nanoparticle arrays (PNPAs) such as nanotriangles, nanohole arrays (PNHAs) and nanocups (NCs). In this research, single layer polystyrene nanospheres (PSNs) are chosen...

In this report, thin film gold supported by PSNs used as electrically enhanced catalysts for the chemical reaction of oxidation of styrene. The products were characterized by using gas chromatography (GC). Oxidation of styrene produced three main products which are benzaldehyde (B), phenylacetaldehyde (PA) and styrene oxide (SO).
