【摘要】 采用微波辅助法在不同掺铁量、不同焙烧温度和不同焙烧时间下制得不同掺铁TiO2光催化材料。运用X射线衍射、紫外可见光漫反射及电感耦合离子体发射光谱仪等多种方法进行表征。结果表明:采用该法铁掺入到了TiO2中,且该法掺铁能够拓宽光谱吸收范围。在获得相同产品的条件下,微波也表现出了更省时的优势。对Fe-TiO2的结构及光催化性能研究表明,掺杂铁离子会抑制金红石型TiO2的生成,能使样品的吸收边带红移,且掺铁量为0.5%的TiO2光催化效果最好。更多还原

【Abstract】 Various Fe-doped TiO2 photocatalytic materials were got by using microwave-assisted synthesis method with different mixed iron content,calcination temperature and calcination time.The characterization used X-ray diffraction line,ultraviolet-visible diffuse reflection,inductively coupled plasma emission spectrometer and other methods.The result indicated that the iron was mixed in titanium dioxide with this method.Besides,the scope of spectral absorption was broaded.Under the background of getting the same product,using microwave was more time-saving.Through the analysis of structure and photocatalytic performance of Fe-TiO2,it showed that doping of iron ion suppressed the formation of rutile type titanium dioxide and could make the sample absorb the sideband redshift.TiO2 with 0.5% of iron can get the best result.更多还原
