Influence of the Metal Nature on the EDL Structure in Propylene Carbonate Solutions of a Surface-Inactive Electrolyte

The curves of differential capacitance and potentials of zero charge of Ga, In–Ga, and Tl–Ga electrodes in propylene carbonate (PC) solutions of a surface-inactive electrolyte are obtained. It is shown that PC is chemically indifferent to these electrodes, mainly because of a lower electron donor ability of its molecules. A metal–PC chemisorption interaction slightly depends on the metal nature and increases in the series Hg = (Tl–Ga) < (In–Ga) < Ga.
