中文摘要 | 本研究主要於水相中合成出高濃度奈米二氧化鈦粒子,並藉由動態光散射原理量測出粒子粒徑分佈多為17nm。另外再以X射線繞射分析儀、氮吸附儀、紫外/可見光光譜儀進行結晶型態、比表面積等物性分析,所得二氧化鈦粒子晶相為銳鈦礦相,BET比表面積達168.96m2/g。最後我們將利用氣相光催化的除臭(反應物為氨氣)反應,證明其光催化效果。 |
英文摘要 | The purpose of this study is the synthesis of titanium dioxide nano particles with high concentration in aqueous solution. Then the particle size measured by dynamic light scattering is about 17nm in diameter. From X-ray diffraction measurement, we found titania particles were anatase, and the BET surface area of TiO2 catalyst was 168.96 m2/g by Nitrogen Adsorption. Finally, the photo-oxidation efficiency of TiO2 catalyst was tested by detector tube to deodorize ammonia under UV light in gas phase. |
