Fabrication and characterization of electrospun orthorhombic InVO4 nanofibers

► In this paper, orthorhombic InVO4 nanofibers were successfully prepared by annealing the electrospun precursor fibers. ► Citric acid was used as a ligand, it could react with metal salts to get a clear homogeneous precursor solution. ► PVP (K-30), one kind of water-soluble polymers, was used as a binder. Meanwhile, PVP was used as a structure guide reagent.
