Chemistry & Biochemistry Theses & Dissertations
The electrochemical behavior of boron-doped diamond microelectrodes has been studied in acetonitrile solutions containing two redox couples using cyclic voltammetry. One test system is 1-2.5 mM ferrocene, containing 0.1 M Tetrabutyl ammonium hexafluorophosphate (TBAH). This well-known reversible redox system involves only one electron transfer with little or no change in the solvation sphere and no breakage/formation of chemical bonds. Another test system is a 1 mM S2Mo180644- solution containing 0.1 M HCIO4. This is one of the most complicated redox systems. In the presence of acid, electrons are usually transferred consecutively and …
