Microwave-assisted synthesis of Mo-doped H_1-xSr₂Nb_3-xMo_xO₁₀（x=0,0.05,0.1,0.15 and 0.2） with high photocatalytic activity

【摘要】 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.更多还原
