What Electrodes Material is Used for Electrochemical Treatment? The selection of electrode materials for electrochemical treatment must take into account issues such as cost, accessibility, stability at the required potentials, selectivity, composition, and pH of the reaction medium, nature of intermediates substances and products, and environmental compatibility. Care has to be taken in the proper selection since most electrodes are useful in only a limited range of potential and pH. With conventional metal electrodes, electroc

Advantages of Electrochemical Processes in Pollution Control In general, electrochemical processes offer many distinctive advantages relative to the other technologies. The following summarizes some of the positive features of electrochemical approaches to pollution control: Environmental compatibility: The main reagent used is the electron, which is a clean reagent, and usually there is no need for adding extra chemicals. Versatility: Electrochemical processes involving direct or indirect oxidation and reduction can generate

Why Ruthenium Oxide Coating Titanium Anode is Used in Chlorine Evolution Reaction(CER)? Due to considerable electrocatalytic activity in the chlorine evolution reaction (CER), ruthenium oxide based electroactive coatings on titanium substrate are used as anodes for the industrial production of chlorine and chlorates. Ruthenium oxide is one of the most active electrocatalysts for the oxygen evolution reaction (OER) since the overpotentials are almost half of that registered on platinum. The coatings are of good catalytic properti

What Factors Affect the IrO2-Ta2O5/Titanium Anode Electrocatalytic Efficiency? It is clear that the electrocatalytic properties of the anode depend significantly on the microstructure of the catalyst, such as surface morphology and phase composition. A larger electrochemically active surface area (ECSA) will also provide more sites for oxygen evolution and thus lead to a lower operating voltage. It is researched that the anodes with 50–70 mol% IrO2 have not only the largest ECSA but also the highest electrochemical activity.
