Abstract

Nucleation and growth of iron clusters inside of nanosized pores of porous polyethylene membrane was investigated. Iron clusters was electrodeposited from 0.1 M FeCl2 at pH=2.0, constant temperature and constant applied potential. Variations of current density vs time durring deposition were recorded. Using Scharifker and Hills theory and normalized equation, experimental data were compared with theoretical curves. Progressive-type nucleation mechanism was found for deposition of iron in domain 850-990 mV of applied potential. A possible alteration of nucleation mechanism was detected at low applied potentials. Control of nucleation mechanism can be used in order to obtain desired nanostructures..
