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。 Microwave-assisted method was used to prepare different doped iron-doped TiO2 photocatalyst materials with different amount of iron, different calcination temperature and different calcination time. X-ray diffraction, UV-visible diffuse reflectance and inductively coupled plasma atomic emission spectrometry and other methods were used to characterize. The results show that this method incorporates iron into TiO2, and this method can broaden the range of spectral absorption. Under the same product conditions, the microwave also showed a more time-saving advantages. The study on the structure and photocatalytic properties of Fe-TiO2 showed that doped iron ions inhibited the formation of rutile TiO2 and red shifted the absorption edge of the sample. The photocatalytic activity of TiO2 with 0.5% iron content was the best.
