Abstract

Electrodeposition of selenium (Se) in an amide type hydrophobic room temperature ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) containing SeCl₄ as a Se source in the presence of excess chloride on a glassy carbon electrode was studied at 25 and 50°C. Raman spectroscopy showed SeCl₄ in BMPTFSA with excess chloride forms an octahedral chlorocomplex of [SeCl₆]^2-. The reduction of [SeCl₆]^2- to Se and that of Se to Se(-II) were observed by cyclic voltammetry. Electrodeposits obtained by potentiostatic electrolysis were confirmed to be metallic Se by energy dispersive X-ray, X-ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy.
