Structural characterization and electrical conductivity studies of BaMoO4 nanofibers prepared by sol-gel and electrospinning techniques

Scheelite type BaMoO4 nanofibers were prepared by using acrylamide assisted sol-gel process and electrospinning technique. The prepared Scheelite BaMoO4 nanofibers were characterized by using TG/DTA, XRD, FTIR, FT-Raman and SEM-EDX techniques. Thermal behavior, crystalline phase and structure of the prepared BaMoO4 nanofibers samples were confirmed from the analysis of the obtained results of TG/DTA, XRD, FTIR and FT-Raman respectively. SEM micrographs along with EDX showed the formation of one dimensional (1D) nanofibers 100-350 nm diameters and existence of Ba, Mo and O elements in the BaMoO4 nanofibers sample. The electrical conductivity of BaMoO4 nanofibers as a function of temperature 200-400 A degrees C under air was evaluated by analyzing the measured impedance data using the winfit software. The newly prepared Scheelite type BaMoO4 nanofibers showed electrical conductivity of 0.92 x 10(-3) S/cm at 400 degrees C.
