Given the importance of tungstate in industry and aiming to introduce new tungstate nanostructure with a modern method, iron tungsten nanofibres were prepared for the first time by sol–gel followed by electrospinning and calcination. First, poly(vinyl alcohol) (PVA) as a matrix polymer was mixed separately with tungstic acid (H 2 WO 4 ) and iron(III) nitrate (Fe(NO 3 ) 3 ). The controlled mixing of the two solutions followed by electrospinning led to the fabrication of PVA/tungstic acid/iron(III) nitrate composite nanofibres. Finally, ceramic nanofibres of iron tungstate were obtained from the calcination of polymeric nanofibres under thermal control conditions. The final product was analysed by scanning electron microscopy, energy-dispersive X-ray spectroscope, Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometer, Brunauer–Emmett–Teller surface area analysis and Barrett–Joyner–Halenda pore size and volume analysis.

使用静电纺丝法制备钨酸铁陶瓷纳米纤维

鉴于钨酸盐在工业中的重要性，并旨在通过现代方法引入新的钨酸盐纳米结构，首次通过溶胶-凝胶、静电纺丝和煅烧制备铁钨纳米纤维。首先，将作为基体聚合物的聚乙烯醇（PVA）与钨酸（H 2 WO 4 ）和硝酸铁（III）（Fe（NO 3 ） 3 ）分别混合。两种溶液的受控混合然后静电纺丝导致了 PVA/钨酸/硝酸铁（III）复合纳米纤维的制造。最后，通过在热控制条件下煅烧聚合物纳米纤维获得钨酸铁陶瓷纳米纤维。最终产品通过扫描电子显微镜、能量色散 X 射线光谱仪、傅里叶变换红外光谱、X 射线衍射、
