Catalytic activities of a novel nanofiber base on molybdenum complex/ α-Fe2O3

Nanocomposite compounds using metal oxides with low loading has already been proven as an effective way to produce new materials with specific properties and high performances. PVA (Polyvinyl alcohol), a synthetic water-soluble hydrophilic polymer, is widely used and studied for nanocomposites technology. Moreover,PVA has unique properties such as good thermal stability, optical properties and oxygen barrier properties. Therefore, this kind of nano-composites are widely used in filters,packaging, tissue engineering scaffolds and CO2 membrane separation application[1]. Electrospinning is a technique using to produce fibrous. The rapidly developing technique of electrospinning has gained surging research interest since the 1990s due to its capability of obtaining nano-fibers. Enormous efforts devoted to explore applications of electrospun nanofibers, such as separation, catalysis, nanoelectronics, sensors, energy conversion/storage, and biomedical utilization[2-3].In this work, nanocomposite PVA/α-Fe2O3/Molybdenum complex on 2- hydroxy naphthaldehyde was synthesized and characterized by Fourier transform infrared (FT-IR) spectroscopy, field-emission scanning electron microscopy (FE-SEM) image, energy dispersive X-ray (EDX) analysis and thermogravimetric analysis/differential thermal analysis (TGA/DTA). Catalytic application of it was investigated in the oxidation of alcohols. 100% of benzaldehyde was obtained in the presence of PVA/Fe2O3/Mo using H2O2 at 80°C for 7h.
