The variations of the equivalent parallel resistance and capacitance of anodic films formed on Ta and Nb in varying concentrations of H2SO4 suggest that the volume of film formed per coulomb is much greater in 100)~, acid, although the dielectric constant is substantially unchanged. The field requir
The influence of Sn on the formation of the corrosion layer on Pb has been studied with a Pb-lO%Sn electrode in 0.5 and 4.5 M sulphuric acid using voltammetry, rrde and potential decay measurements, as well as photoelectrochemistry and ac impedance. The results obtained support the conclusion that i
Cyclic voltammetry (CV), amperometric it experiments, and electrochemical impedance spectroscopy (EIS) measurements were carried out by using glassy carbon disk electrode covered with the Pt/C catalyst powder in solutions of 0.5 mol L -1 H 2 SO 4 containing 0.5 mol L -1 CH 3 OH and 0.5 mol L -1 H 2
