The Performance of RuO2 and IrO2 Coating in Electrolysis Process Dissolution of the electrocatalytic coating can lead to electrode failure. An Increase in the anode current density due to partial removal/wear of coating from the substrate is dissolution. The pH of electrolytes and electrolyte impurities also influences coating dissolution. In highly oxidizing environments, RuO2 is unstable and tends to oxidize to higher oxidation states. In acidic electrolytes, RuO2 tends to oxidize to soluble RuO3 or volatil

Why the Stability of Coated Titanium Anode is Important? The need for a stable electrode for the chlorine-alkali industry led to the invention of the coated titanium anode, and so the importance of electrode coating stability can not be overemphasized. The stability of an electrode may be defined in terms of its lifetime. It measures the time it takes for the coated oxide electrode to be deactivated or fail in the electrolysis cell. For coated titanium anodes, stability is the ability of the electrode to function effectively in the

How to Prepare Coated Titanium Anodes through the Thermal Decomposition Method? Thermal decomposition methods have been adopted to prepare coated titanium anode, a few micrometers of the oxide layer are deposited on titanium substrate. These oxides are seldom used alone, they are usually doped or mixed with less active oxides of higher chemical stability. Thermal decomposition preparation of MMO coated titanium anode is achieved thermochemically by dissolving the suitable metal salts in a solvent (alcohol or acidified water). Th

How to Select an Appropriate Electrode Coating in the Electrolysis Process It is generally accepted that a good catalyst for the oxygen evolution reaction (OER) must have a relatively high electronic conductivity, high affinity for adsorbed hydroxide intermediates and the electrode must be resistant to corrosion. Noble metal oxides of Ru, Ir, Rh, etc. are considered to be good electrocatalysts for the OER. However, noble metal oxide coatings can dissolve when exposed to harsh industrial conditions such as higher current densities (
