Abstract
The experimental and theoretical limits of superheat of water in hot-wire electrochemistry were determined. The maximum attainable temperature was ca. 250 °C during 5 ms heat pulses. The temperature–time curves were simulated by means of a new numerical calculation procedure, which took into account the temperature dependence of most physical data of water and the platinum wire. Temperature pulse voltammograms of cupric species were recorded. With 5 ms heat pulses a drastic increase in peak current and an improved signal-to-noise ratio was obtained.
