A Study of Photocatalysis of Methylene Blue of TiO2 Fabricated by Electric Spark Discharge Method

摘要: This study used the Electric Spark Discharge Method (ESDM) to prepare nano-Ti colloid. The results showed that process efficiency increased according current and selecting different discharge periods ( - ). preparation is pollution-free very contributive using TiO2 for photocatalytic reaction degrade organic compounds. 99.9% pure Ti metal examine effects of parameter settings on photocatalysis methylene blue. experimental period ) has an effect characteristics prepared colloid but affects its concentration. colloid, as under parameters, poor with blue at concentration 50 mg/L. does not have favorable degrading above For a low 10 mg/L, 100-100 preferable. high 30 mg/L, exceeding 100 fixed better. As by ESDM was free chemical agents, when in compounds, there no secondary pollution environment.
