ATO Titanium Anode(SnO2-Sb2O5) for Wastewater Treatment Antimony-doped tin oxide (ATO) coated on titanium is one of the most studied anode materials for wastewater treatment. Denoted as Titanium /SnO2-Sb2O5, this anode material is an inactive DSA-type of electrode material, so the oxygen evolution reaction can be suppressed to allow the degradation of organic compounds by hydroxyl radicals. Antimony-doped tin oxide is more efficient in the oxidation of organics than other DSAs with noble metals. Although the efficiency is not

How Mixed Metal Oxide Coated Titanium Anodes Applied in Electrochemical Industry? Titanium based mixed metal oxide anodes have played an important role in the electrochemical industry. They are essentially mixed metal oxide films deposited on titanium and have been used to replace the conventional graphite electrodes. With long service life and allowing higher current densities, they are named“dimensionally stable anodes” because their material is not consumed during electrolysis, unlike graphite anode. The mixe

Why BDD Anode is Not Widely Used in Electrochemical Wastewater Treatment? Boron-doped diamond (BDD) is a novel material with distinctive characteristics. BDD was found to be superior in the anodic oxidation of organic compounds over many other anode materials. For example, in a study comparing the ability of BDD and SnO2 anodes towards oxidizing various dyes, the current efficiency on BDD was generally 2-3 times higher than was obtained on SnO2. The high oxidation ability was associated with high oxygen evolution potential. On B

Why Traditional Carbon Anode is Not a Good Choice for Electrochemical Wastewater Treatment? Traditional carbon based anodes, such as graphite and glassy carbon, have the advantages of being a low-cost anode material. They can also be made with a large surface area, in the form of reticulated carbon or a packed bed. Their use is limited because carbon based anodes are known to be consumed during the electrolysis, which adds to the increase in the inter-electrode gap with a subsequent increase in solution resistance and a waste of
