TL;DR: In this article, the degradation of Ti2RuFe occurs because of hydrogen absorption and desorption during alternating hydrogen discharge and opencircuit conditions, and various hypotheses to explain the increase stability of the O containing alloy are considered.
Abstract: Ti2RuFe and Ti2RuFeO2 nanocrystalline alloys were prepared by high energy ball-milling and used as cathodes for the hydrogen evolution reaction (HER) in the process of sodium chlorate synthesis. Ti2RuFe is almost single phase with the B2 structure. In contrast, Ti2RuFeO2 is made of a mixture of Ti2RuFe and TiOx phases. Tests in chlorate electrolysis conditions did not show any sign of degradation of Ti2RuFeO2 over a 300 h period, while Ti2RuFe breaks down after less than 100 h. The degradation of Ti2RuFe occurs because of hydrogen absorption and desorption during alternating hydrogen discharge and open-circuit conditions. Various hypotheses to explain the increase stability of the O containing alloy are considered.

TL;DR: In this article, a new cleaner production process for producing sodium chlorite by reducing sodium chlorate with hydrogen peroxide was presented, where the by-produced sodium sulfate in sulfuric acid was minimized and reclaimed.

TL;DR: In this paper, the authors examined the reaction paths governing chlorine dioxide formation from solutions of sodium chlorate, sulfuric acid, hydrogen peroxide and sodium chloride at 25°C and found that the rate of the chloride-chlorate path predominated and was enhanced by hydrogen peroxidation.
Abstract: Reaction paths governing chlorine dioxide formation from solutions of sodium chlorate, sulfuric acid, hydrogen peroxide and sodium chloride at 25°C were examined. Chlorine dioxide was formed by two paths: the reduction of chlorate by hydrogen peroxide and the reduction of chlorate by chloride. At conditions of this study, the rate of the chloride-chlorate path predominated and was enhanced by hydrogen peroxide, reaching an upper limit as hydrogen peroxide concentration was increased. A mechanism was proposed that explains the observed behavior. It is based on existing theory, but includes a new step: the rapid reaction of hydrogen peroxide with an intermediate, Cl2O2. It was shown also that chloride was not required to sustain chlorine dioxide formation in the hydrogen peroxide-chlorate path.
