The ability to control the shape and size of nanocomposites is an important factor for defining their properties, such as the electronic band gap, conductivity, and light-emission efficiency [27].Recently, it was found that chloroaurate ions (AuCl4???) could also be applied as an oxidant in the oxidative polymerization of pyrrole, leading to gold nanostructures capped with polypyrrole [28,29].
