报道了银配合物在乙腈和单相超临界二氧化碳/乙腈（scCO2/CH3CN）体系中的循环伏安法。研究了五种银前体：（1,5-环二烯）（六氟乙酰丙酮）银(I) [Ag(hfac)(COD)]、（六氟乙酰丙酮）（三苯基膦）银(I) [Ag(hfac)(PPh3)]、（全氟辛烷）双（三苯基膦）银(I) [Ag(CF3(CF2)6CO2)(PPh3)2]、四（三苯基膦）银(I)四氟硼酸盐[Ag(PPh3)4][BF4]和四（乙腈）银(I)四氟硼酸盐[Ag(CH3CN)4][BF4]。其中，[Ag(CH3CN)4][BF4]最适合于scCO2/CH3CN电沉积银。
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.
