Methods for morphology control in a process of nanostructures growth by deposition of atoms diffusing from solution to the forming surface are developed. Surface restructuring is considered, yielding morphologies of interest in catalysis. Shape selection for nanoparticles and surface nanostructures occurs in appropriate "nonequilibrium" regime of properly balanced rates of various processes.
Scientific interest in noble metals nanoparticles (NPs) and nanostructured metal surfaces formed by their deposition is caused by their unique physical properties, including surface enhancement of linear and nonlinear optical phenomena in the media in contact with such nanostructures. Morphological characteristics of NPs determine their catalytic, sensor, optical properties. Thus, it is of great importance to identify factors that affect the morphology of nanoparticles formed in multicomponent solution with regard to kinetic phenomena in solution and on the NPs surface.
