摘要 用高压静电纺丝和程序焙烧的方法,制备了具有棒状或颗粒形貌的α-K7P2W17NbO62。红外光谱(FT-IR),X-射线粉末衍射(XRD)进行了表征,结果表明获得了纳米尺寸的α-K7P2W17NbO62。扫描电子显微镜照片(SEM)显示:PVA/α-K7P2W17NbO62纤维毯在340℃条件下焙烧,保温时间从6h到12h,随着时间的延长,多金属氧酸盐α-K7P2W17NbO62的形貌由纤维到棒状最后形成颗粒状形貌。 The nanogains or nanorods of α-K7P2W17NbO62 were obtained through electrospun and calcinations methods. FT-IR spectroscopy and XRD showed that nano-size polyoxometalates was still remained α-K7P2W17NbO62. SEM images shown fibrous PVA/α-K7P2W17NbO62 had been calcined at 340℃ from 6 h to 12 h,the various morphologies of α-K7P2W17NbO62 from rods to particles were observed.
