Mixed Metal Oxide Coating for the Electrochemical Process Mixed metal oxide coatings on titanium plates are widely used as anodes in a variety of electrochemical processes like chlorine generation in the Chlor-alkali industry, oxygen production, electrowinning of metals, and cathodic protection. Noble metal oxides such as RuO2 and IrO2 with high conductivity and electrochemical activity have received considerable attention in the electrochemical industry as electro-catalyst. For further improvement instability of these oxides, o

How Dimensionally Stable Anodes Used for Electrochemical Wastewater Treatment? Dimensionally stable anodes (DSAs) have been investigated in electrochemical wastewater treatment. They typically consist of mixed metal oxide coatings on valve metal substrates. The functionality and selectivity of these electrodes are highly dependant on their physical structure and composition. These anodes conventionally use titanium as the substrate with either IrO2 or RuO2 as the electrocatalyst and TiO2, Ta2O5, ZrO2, or SnO2 as the stabilizer that

Why Titanium is Used as the Substrate of Dimensionally Stable Anodes? Titanium is commonly used as the substrate material for dimensionally stable anodes because it is not easily dissolved under anodic polarization in aqueous environments. The stability of titanium can be attributed to the compact oxide film that forms on its surface. This film forms naturally in the air, but forms more rapidly when the metal is polarized to an anodic potential in an aqueous electrolyte. Using titanium as the substrate for a DSA increases the

What is Electrochemical Water Disinfection? Electrochemical water disinfection can be defined as the elimination of microorganisms from a water sample using the passage of electrical current through that sample. Here the electrode materials are very important because upon application of the electrical current electrochemical reactions occur at the surface of the electrodes. At the cathode, hydrogen gas is produced, and at the anode, oxygen gas is produced along with oxidizing compounds that can include ozone, free chlorine, peroxid
