Abstract

Abstract : Indium(iii ) is electrodeposited from organic electrolytes, in which indium(i ) occurs as an intermediate species, and disproportionates to indium(iii ) and indium(0) in the form of nanoparticles. Abstract : The electrochemical behaviour and deposition of indium in electrolytes composed of 0.4 mol dm −3 In(Tf2 N)3 and 0.4 mol dm −3 InCl3 in the solvents 1, 2-dimethoxyethane and poly(ethylene glycol) (average molecular mass of 0.400 kg mol −1, PEG400) was investigated. Indium(i ) was identified as the intermediate species that disproportionated to indium(iii ) and indium(0) nanoparticles. The presence of nanoparticles was verified by TEM analysis. SEM analysis showed that deposits obtained at room temperature from 1, 2-dimethoxyethane were rough, while spherical structures were formed in PEG400 at 160 °C.
