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 (

The Superiority of MMO Coated Titanium Anode over Graphite Anodes in Chlor-alkali Industry MMO coated titanium anodes are composed of conducting titanium substrate coated with an activated oxide layer which can catalyze a particular electrochemical reaction. The catalysts are mainly made up of platinum group metal oxides (such as RuO2 and IrO2) mixed with other nonprecious metal components, such as additives likeTiO2 and Ta5O5.   MMO coated titanium anodes have been used in the electrochemical industry like chlorine and oxy
