Efficient synthesis of niobium pentoxide nanowires and application in ethanolysis of furfuryl alcohol.

ABSTRACT: Nb₂O₅ nanowires with high specific surface area and crystallinity were prepared by using ammonium oxalate and an acetic acid solvent system. The nanomaterial was applied in ethanolysis of furfuryl alcohol (FA), and the yield of the product, 2-(ethoxymethyl)furan (FEE), achieved was up to 79.6%. Compared to mesoporous Nb₂O₅ materials and other porous materials, the residence time of FEE on the surface of the catalyst is shorter, and the yield of ethyl levulinate (EL) is lower. Furthermore, a high temperature calcination treatment can change the acid sites and acidity type distribution on the nanowire surface. By XRD, NH₃-TPD, IR, and TG-DTA determination methods, it was found that the weak and medium-strong acid sites on the surface of
