摘要

研究了钛负载RuO2TiO2电极在HClH2SO4溶液中的降解行为。在电解初期，电极表面裂纹是由强酸化介质中氧化物的溶解而形成的，其质子浓度受主电解反应控制。结果表明，氧化物中的钛成分是导致裂纹中氧化物溶解的主要原因。

Degradation behaviour of a titanium supported RuO2TiO2 electrode

The degradation behaviour of a titanium supported RuO₂TiO₂ electrode in HClH₂SO₄ solutions is investigated. In the early stage of electrolysis cracks on the electrode surface grow by dissolution of oxide in the strongly acidified medium, the proton concentration of which is controlled by the main electrolytic reactions. It is concluded that the titanium component in the oxide is responsible for the dissolution of the oxides in the cracks.
