Abstract
The cyclic voltammetric studies of the sulphate and oxalate complexes of Tii+/Ti3+ redox systems
on Cu electrodes are reported and the results are compared with the behaviour on Hg and GC electrodes
reported earlier. The easily reducible sulphate complexes are formed only on high Ti+ and
H2SO4 concentrations as noticed in the earlier studies. The apparent heterogeneous charge transfer
rate constant (kho) decreases by 40 times on Cu when compared to Hg. This rather unusual observation
is probably associated with the greater blocking effect of the supporting electrolyte anions on
Cu when compared to Hg. Added Cl-as well as so4'- exert even stronger blocking effect. The possible
implication of the present study on the indirect electro-reduction technique used for the nitro compound
reduction using Tii+/Ti3+ redox system is also discussed in some detail.
