High-Performance COD Detection of Organic Compound Pollutants using Sulfurized-TiO2/Ti Nanotube Array Photoelectrocatalyst
Photoelectrochemical oxidation processes offer a highly sensitive method to detect organic pollutants from wastewaters. Photoactive semiconducting material is the key factor in this process that accelerates the oxidation of the organic pollutant agent for sensitive detection. Chalcogenide-doped TiO...
