| 제목 | Utilizing TiO2 nanotube composite Materials as an Efficient Air Purification System |
| 초록 | Air pollution is one of the biggest challenges we face in the 21st century. Here we propose a photocatalytic approach to convert volatile compounds in a cost effective way. The quality of indoor air has a direct impact on human health in terms of lengthened exposure to pollutants by inhalation. Despite the importance of indoor air quality, only a few studies have reported on the feasibility of applying photocatalytic technology for removal of indoor air pollution. The feasibility of applying photocatalytic technology for removal of nitrogen oxide (NO) and volatile organic compounds (VOCs) at typical indoor air level using TiO2 were investigated by several other research groups. In this work we are focusing to photo catalytically convert volatile organic compounds by TiO2 nanotubes. Here we report the fabrication, structural analysis and photocatalytic properties of TiO2 nanotube prepared by electrodeposition. Anodization to form tube layers is usually carried out by applying a potential step (or ramp) at a constant voltage between 1–30 V in aqueous electrolyte or 5–150 V in nonaqueous electrolytes containing approximately 0.05m–0.5m (0.1–1 wt%) fluoride ions (and usually some background ion species). The growth of the oxide can then be monitored by recording the current–time characteristics. |
