AgNbO3的水热合成和光催化性质表征

Hydrotherml synthesis and photocatalytic activity of AgNbO_3

采用水热合成法制备了AgNbO3粉末,运用XRD(X-ray diffraction),SEM(Scanning Electron Microscope)和UV-Vis DRS(diffuse reflectance spectroscopy)对其表征.在可见光照射下通过降解亚甲基蓝,来评估样品的光催化活性,实验结果表明,目标化合物与固相合成法制备的AgNbO3相比较具有明显较高的催化活性,水热法制备的产物在光催化方面拥有广阔的应用前景.

AgNbO3 powders were synthesized by mild hydrothermal condition. The sample was characterized by X-ray diffracion （XRD）, Scanning Electron Microscope （SEM） and UV-Vis diffuse reflectance spectra （UV-Vis DRS）. The photocatalytic activity of AgNbO3 powders were evaluated by degradation of methylene blue under visible light irradiation. The results showed that the titled compounds exhibit a stronger enhancement of photocatalytic activity than solid state reaction-AgNbO3 at room temperature, which have potential future applications in photocatalysis.
