Effect of Sintering Temperature on the Photocatalytic Activity of Flower-Like Bi2WO6
钨酸铋在水相体系中能光催化降解有机污染物,而对于钨酸铋光催化活性影响因素的研究非常少.本文研究了煅烧温度对花朵状钨酸铋光催化活性的影响.以钨酸钠和硝酸铋为原料,在160°C下水热反应20 h,合成催化剂,并经不同温度煅烧3 h.用X射线衍射(XRD)、拉曼(Raman)光谱、紫外-可见漫反射吸收光谱(UV-Vis DRS)和荧光(PL)光谱表征样品.结果表明,这些样品具有十分相似的相组成和电子结构.然而,对于水中苯酚的降解,钨酸铋的光催化活性显示…查看全部>>
Bi2WO6 is reportedly active for the photocatalytic degradation of organic compounds in aerated aqueous solution, but factors influencing the photocatalytic activity of pristine Bi2WO6 have received little attention. In this study, the effect of sintering temperature on the physical properties of flower-like Bi2WO6 was investigated. The catalyst was synthesized through the hydrothermal reaction of Na2WO4 and Bi(NO3)3 at 160 ° C for 20 h, fol owed by sintering…查看全部>>
