Electrodeposition of Tin from 1-Methyl-3-ethylimidazolium chloride/AlCl{sub}3/SnCl{sub}2 Room Temperature Molten Salts

摘要

The electrodeposition of tin was investigated in the room temperature molten salt based on 1-methyl-3-ethylimidizalium/AlCl{sub}3/SnCl{sub}2. The results show that the morphology and size of the tin crystallites are strongly influenced by the composition of the melts and the deposition potentials, producing tin deposits with different shapes and widely various size ranges from several micrometers to nanometers. Double potentiostatic pulse deposition technique has been used to control the morphology and particle size of tin deposits. Nano-size tin particles around 50 nm with more regular shape and uniform size distribution can be obtained successfully by a balanced control of the nucleation and growth of the tin deposits.
