| 摘 要： | 通过微波辅助法制备出高活性H1-xSr2Nb3-xMoxO10光催化材料，制备过程和时间均被大大缩短。采用X射线粉末衍射（XRD）、扫描电镜（SEM）、紫外-可见吸收吸收光谱（UV-Vis DRS）等表征其材料性能。考察了催化材料在40W汞灯辐照下催化降解甲基橙的催化性能。实验结果表明，MoO3的掺入量为15%（摩尔分数）时，材料的光催化性能最优。

| Abstract: | H1-xSr2Nb3-xMoxO10 photocatalysts were synthesized using a microwave-irradiation-assisted ionexchange reaction. The physicochemical properties of the photocatalysts were analyzed by field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and ultraviolet-visible spectroscopy (UV-vis). The photocatalytic activity of the H1-xSr2Nb3-xMoxO10 was evaluated by degrading methyl orange (MO) dye under light irradiation from a 40-W mercury lamp. The results proved that the Mo doping amount had an important effect on the photocatalytic activity of the catalysts. The highest photocatalytic activity was obtained when the doping amount was 15 mol%. Furthermore, the complex preparation process and lengthy time was simplified and shortened greatly. |
