What Factors Affect the IrO2-Ta2O5/Titanium Anode Electrocatalytic Efficiency?
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)?
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 (
Comparison of Electrode Materials for Degrading Organic Pollutants
Comparison of Electrode Materials for Degrading Organic Pollutants Strong oxidant species like hydroxyl radicals, atomic oxygen, hydrogen peroxide, perhydroxyl radicals, and free chlorine are produced in the electrochemical reactions. These powerful oxidizing agents are capable of degrading organic pollutants and kill the bacteria. By electrolysis of water, anodic catalysis to produce adsorbed hydroxyl radicals. The electrode material strongly affects the production of reactive species such as Cl2, OCl- , H2O2, ozone, &mid
What is Fenton Reaction and Application?
What is Fenton Reaction and Application? The Fenton reaction involves the following sequence of major steps: Fe2+ + H2O2 → Fe3+ + OH– + ·OH Fe3+ + ·OH → Fe3+ + OH– H2O2 + ·OH → · HO2 + H2O Fe2+ + · HO2 → Fe3+ + HO2 - Today, Fenton’s process is used to treat a variety of industrial wastes containing a range of toxic organic compounds (phenols, formaldehyde, BTEX, and complex wastes derived from dyestuffs, pesticides, wood preservatives, plastics additi
