光催化的Ag掺杂TiO_2制备表征与吸收特性
Preparation characterization and absorption of Ag-doped TiO_2 based on photocatalysis
摘要
Abstract
The processes of TiO2 and Ag-TiO2 colloid prepared by sol-gel method is investigated.Keeping pH value steady and production processes different,the samples are prepared by using tetrabutyl titanate as precursor of titanium source,AgNO3 as silver source and KH—550 as dispersing source.The samples are tested and characterized by scanning electron microscopy（SEM）,X-ray diffraction（XRD）,nanoparticle size analyzer and ultraviolet and visible spectro-photometer（UV-vis）.The results show that the absorption band of Ag-TiO2 sample widen and its absorption strength increase on the preparation conditions： the ratio of mole mass of Ag to TiO2 is 5% and mixing KH—550 with 0.3 milliliter,stirring and dehydrate at 50 ℃,and heat at 600 ℃.关键词
