The physicochemical properties of the photocatalysts were analyzed by field-emission scan- ning electron microscopy （FE-SEM）, X-ray diffraction （XRD） and ultraviolet-visible spectroscopy （UV-vis）. The photocatalytic activity of the Hl-xSr2Nb3-xMox01o 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 photoeatalytic activity was obtained when the doping amount was 15 mol%. Furthermore, the complex preparation process and lengthy time was simplified and shortened greatly.展开更多
