What Cause the Destruction of MMO Anodes? The lifetime of MMO anodes is affected by the electrocatalytic layer, which is conductive. It is corrosion resistance against the electrolyte like fluorides, bromides, cyanates, and nitrites. The roughness of this active coating layer affects the current density and kinetics of electrochemical reactions that in turn determine the operating potential of the electrode surface and the stability of the coating. Per MMO anode for oxygen evolution in acid solutions, the destruction of platinum

What Factors Affect the Activity of MMO Anodes? Surface between electrocatalytic layer and base metal and surface between electrocatalytic layer and solution are two crucial interfaces for MMO anodes. The efficiency of electrocatalyst impacts both inner qualities of the system and the real active area of system. Anode manufacturing elements that result in anode activity are dissolved salts and solvent, concentration of solutions, spread technique of solution, number and thickness of coating layers, heat treatment tim

How RuO2 IrO2 Ta2O5 Coated Anode Used in Electrochemical Fields? Mixed metal oxide anodes consist of a mixture of active oxide and inert oxide that stabilizes the anode. In the development of anodes, the focus has been on long-time durability and selectivity. The anode qualities can’t be actually modified by changing the active component because there is only a limited number of alternative replacements to active compounds like ruthenium oxide and iridium oxide. For that reason, the development of anodes has often focused on

What Factors Affect the Efficiency of MMO Anodes? Mixed Metal Oxide(MMO) anodes are featured for low electrical resistance, good electrochemical activity, corrosion resistance, and dimensional stability. Low electrical resistance reduces energy consumption in the electrochemical process.   The MMO anode properties are mainly determined by pretreatment of the base metal before it is coated by electrochemically active oxide layer, heat treatment temperature, amount of metal per deposition cycle, and thickness of the coating l
