제목 | Application of As(Ⅲ) oxidation using the charging system of TiO2 and WO3 photocatalysts |
초록 | This study investigated TiO2 and WO3(TW) composite-embedded inorganic membrane system for As(Ⅲ) oxidation and used a flow system in dark conditions. Membrane filters charged TW were charged under UV or solar light irradiation. The electrons accumulated on TW were utilized for producing ROSs(Reactive oxygen species), which successfully enables As(III) oxidation. Also, This was influenced by reaction conditions (Air, N2, O2), irradiation time and the amount of WO3. TW membrane can be easily reused after recharging process without the requirement of additional physical separation steps. This research was supported by the Basic Science Research Program (2019R1A2C2002602), the Technology Development Program to Solve Climate Changes (2019M1A2A2065616) and Next-Generation Carbon Upcycling Project (2017M1A2A2043123) through the National Research Foundation, Korea. |
