The solid state oxidation kinetics of Pb–Sn single-phase (2.5 at. % Sn) and eutectic alloys were studied with Auger Electron Spectroscopy combined with sputter depth profiling. The single-phase samples were oxidized in air in the temperature range 22 °C to 250 °C, while the eutectic samples were oxidized from 22 °C to 175 °C. Both alloys oxidize logarithmically between 22 °C and 90 °C and parabolically at temperatures greater than 120 °C. The activation energies for the parabolic oxidation of the single-phase and eutectic alloys are 69.5 and 67.1 ± 8 kJ/mole, respectively.

The oxidation kinetics of the AK12M2 aluminum alloy modified to 1.0% by barium was studied using thermogravimetry method. It was shown that the addition of barium to the alloy and the increase in temperature increase the oxidation rate of the initial alloy in the solid state. The apparent activation energy of the oxidation process of the AK12M2 aluminum alloy is 127.73 kJ/mol and decreases to 71.85 kJ∕mol for the alloy with 1.0% barium. The oxidation curves of the AK12M2 aluminum alloy with barium in the solid state are described by polynomials indicating the hyperbolic mechanism of that process. The mechanism of influence of barium on the oxidability of the AK12M2 aluminum alloy was established. It lies in the fact that barium in the range of 0.3-1.0% plays a dominant role in the formation of an oxide film, which is characterized by low protective properties. Barium influence is explained by its physicochemical properties as one of the alkaline earth metals.

<p><i>Operando</i> spectroelectrochemical analysis is used to determine the water oxidation reaction kinetics for hematite photoanodes prepared using four different synthetic procedures. Whilst these photoanodes exhibit very different current / voltage performance, their underlying water oxidation kinetics are found to be almost invariant. Lower photoanode performance was found to correlate with the observation of optical signals indicative of charge accumulation in mid-gap oxygen vacancy states, indicating these states do not contribute directly to water oxidation.</p>
