Abstract : Capacitances measured on tungsten bronze electrodes have provided new information about the electronic properties of the semiconducting surface layer. Both the donor concentration and the flat bond potential are altered by platinum doping. Further evidence has emerged from the work to support the view that the bronze surface undergoes a reversible change in the vicinity of 1.1.3 volts vs. RHE, which may involve the incorporation of oxygen atoms at the more anodic potentials, and their reduction to water at the more cathodic potentials.
