Abstract

Cyclic voltammetry of silver coordination complexes in acetonitrile and in a single-phase supercritical carbon dioxide/acetonitrile (scCO₂/CH₃CN) system is reported. Five silver precursors are investigated: (1,5-cyclooctadiene)(hexafluoroacetylacetonato) silver(I) [Ag(hfac)(COD)], (hexafluoroacetylacetonato)(triphenylphosphine) silver(I) [Ag(hfac)(PPh₃)], (perfluorooctanoato)- bis(triphenylphosphine) silver(I) [Ag(CF₃(CF₂)₆CO₂)(PPh₃)₂], tetrakis( triphenylphosphine) silver(I) tetrafluoroborate [Ag(PPh₃)₄]- [BF₄] and tetrakis(acetonitrile) silver(I) tetrafluoroborate [Ag- (CH₃CN)₄][BF₄]. Of these, [Ag(CH₃CN)₄][BF₄] is found to be the most suitable for electrodeposition of silver from scCO₂/CH₃CN.
