Electrochemical behavior of aqueous isopolymolybdates at various pH (0.1–8.7) is addressed in dropping mercury electrode experiments. Formation of compact adlayers is found to be responsible for decreased current of molybdate reduction (self-inhibi

V(V)-mixed addenda Keggin tungstophosphate demonstrates the pronounced dependence of polarographic half-wave potential E1/2 at positively charged mercury surface on the nature of supporting alkali metal cation. This effect (typical for polyoxometalat

The kinetics of single electron heteroatom reduction in Ce(IV)-decatungstate anion is demonstrated to be strongly dependent on the nature of the supporting electrolyte cation. DC polarography reveals an increase of both reduction rate at a positively

We extend the technique of preparing oxotungstate thin films by cathodic electrocrystallization from metastable acidic solutions to fabricate vanadium- and molybdenum-doped films on platinum and fluorine-doped tin oxide (FTO). By means of cyclic volt
