| 摘 要： | 基于TiO2光催化剂的催化机理尚不明确, 因此发展一种具有不同波段的光催化材料对光催化机理的研究至关重要. 本文采用溶胶-凝胶方法合成了一个Fe3O4掺杂的金红石型TiO2复合物, 通过红外、粉末衍射以及扫描电镜对其结构进行了表征. 紫外-可见吸收光谱表明, 无论在可见光或者是紫外光的照射下, 它都表现出良好的光催化性能, 说明Fe3O4掺杂对改善TiO2的催化性能有一定影响.

| Abstract: | TiO2-based photocatalyst has been widely reported, but the catalysis mechanism is not clear, so it is significant to develop photocatalytic materials upon irradiation with different light. In this paper, the Fe3O4-doped TiO2 complex was synthesized and its structure was characterized by infrared spectra, X-ray diffraction and scanning electron microscope. The UV-Vis absorption spectra showed that the complex had excellent photocatalytic performance upon irradiation with visible light or ultraviolet light. It suggests that the doping of Fe3O4 has a certain effect on improving the catalytic performance of TiO2. |
