Fabrication of two-dimensional staggered silver nanosheets on an aluminium foil

Two-dimensional staggered silver nanosheets (NSs) immobilized on a flat aluminium foil have been synthesized by keeping the underside surface of the foil in contact with the solution of normal silver mirror reaction. The NSs are hundreds of nanometres to several micrometres in dimensions and tens of nanometres in thickness. The effects of the aluminium foil, a chemically active substrate, on the orientation growth of silver nanosheets has been revealed. The results demonstrated that the growth and the morphology control of the silver nanostructure were simply realized in one process by the introduction of a chemically active substrate.
