三电极体系中,有用Ag disk做参比电极的吗?

文献上是这么写的:Cyclic voltammetry measurements were performed on a computer-controlled Autolab P20 electrochemical workstation (Eco Chimie, Netherlands) in combination with a conventional three-electrode, one-compartment electrochemical cell. A dyecoated nanocrystalline TiO2 film in the absence (electrode A) or presence (electrode B) of GBA cografting was employed as the working electrode. A Pt foil and an Ag disk were used as counter and reference electrodes, respectively. The reference electrode was calibrated by measuring the redox potential of ferrocene dissolved in 1-methyl-3-ethylimidazolium bis (trifluoromethyl) sulfonyl) imide (EMITFSI), and the redox potentials were converted to those vs a normal hydrogen electrode (NHE) reference scale by adding a constant of 0.67 V. 这里参比用的就是Ag disk,电解液是离子液体,是非水体系。 [ Last edited by pj2008 on 2008-5-11 at 22:57 ] |
