제목 Synthesis of metal coupled N-TiO2 nanoparticles by using reductant for development of photocatalytic activity
초록 Titanium dioxide(TiO2) is useful material which remove the organic pollutant from both air and water. Generally, catalytic activity increases as doping with non-metal or loading metal particles on the TiO2. In this study, metal particles were attached on the N doped TiO2 surface by using sodium borohydride as a reducing agent. Reducing agent has effects on the reduction rate that the more amount and smaller metal particle could be attached on the N-TiO2 surface. The photocatalytic activity of metal coupled N-TiO2 was also evaluated when using the reducing agent. Transmission electron microscope and UV-Vis spectrophotometer were used to observe the amount of metal particles attached on the surface. The photocatlytic activities of as-prepared samples were characterized by the decoloration of aqueous MO or MB solution under Xenon light source. Toluene or p-xylene were selected for target VOC material to measure of decomposition and monitoring the concentration under UVLED irradiation in a closed chamber system.
