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.

Why IrO2 Ta2O5 Coating on Titanium Substrate is the Best Anode for Oxygen Evolution Reaction (OER)? Efficient electrowinning (EW) in aqueous sulfate electrolytes depends on fast reaction kinetics, low ohmic resistance, and suppression of parasitic and detrimental reactions. The overall cell voltage is determined by the thermodynamic potentials for metal deposition (cathode) and oxygen evolution (anode), in addition to overpotentials and ohmic voltage drops. The sluggish reaction kinetics of the oxygen evolution reaction (
