L'invention concerne un procédé de synthèse combinée d'anodes dimensionnellement stables avec une couche active TixOy/Pt sur des substrats métalliques en titane, qui consiste à déposer par électrolyse une fine couche de platine sur le substrat suivi d'un traitement termique à l'air, ce qui permet de contrôler la composition et les propriétés des matériaux obtenus. Le traitement thermique entraîne des changements significatifs dans la morphologie de surface, en raison de la distribution du Pt sur la surface et dans la masse due à la diffusion et au frittage, ainsi qu'à une augmentation du degré de cristallinité. Les principales régularités des processus se produisant lors de l'oxydation des ions chlorure sur la surface du platine ont été étudiées ainsi que l'activité catalytique et la sélectivité du platine dans la synthèse anodique de l'hypochlorite ont été déterminées. Les résultats obtenus ont été montrés que la formation de chlore et d'hypochlorite se déroule avec la participation de particules labiles contenant de l'oxygène. Il a été démontré que les trois principaux processus parallèles sont réalisés lors de l'électrolyse du NaCl : i) oxydation du Cl- en hypochlorite ; ii) chlorate et iii) la réaction d'évolution de l'oxygène.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A method for the combined synthesis of dimensionally stable anodes with an active TixOy/Pt layer on metallic titanium substrates is proposed, which consists of electrolytically depositing a thin layer of platinum on the substrate followed by termal treatment in air, which allows one to control the composition and properties of obtained materials. Thermal treatment leads to significant changes in the surface morphology, because of distribution of Pt over the surface and in the bulk due to diffusion and sintering, as well as an increase in the degree of crystallinity. The main regularities of the processes occurring during the oxidation of chloride ions on the platinum surface have been investigated as well as the catalytic activity and selectivity of platinum in the anodic synthesis of hypochlorite has been determined. The results obtained have been shown that the formation of chlorine and hypochlorite proceed with the participation of labile oxygen-containing particles. It has been shown that the main three parallel processes are realized during the electrolysis of NaCl: i) oxidation of Cl- to hypochlorite; ii) chlorate and iii) the oxygen evolution reaction. 84 pp. Englisch.
