Abstract
Two types of redox processes, with the formation of (a) dissolved reduced forms of tungstates and (b) solid products, occur on a platinum electrode in metastable long-lived true solutions of isopolytungstates (pH ∼ 0.5) in the hydrogen adsorption region. The solid products accumulate on the platinum surface as crystalline films capable of reversible recharging. Basic parameters of the films are determined using cyclic voltammetry, x-ray diffractometry, and scanning tunneling microscopy. Based on a spectrophotometric analysis of solutions, redox conversions, observed in the hydrogen range of potentials, are referred to dissolved hepta- and decatungstates present in the system.
