Two approaches were employed with different electrospun solution compositions and inorganic precursors. Thorium nitrate with polyvinyl alcohol (PVA) as a supporting polymer was successfully electrospun from an aqueous solution resulting in green composite fibers that were calcined at 773 K to pure ThO2 nanofibers of diameter 76 +/- 25 nm. Another precursor solution was based on organic solvents and thorium acetylacetonate complex with polyvinylpyrrolidone (PVP). Green fibers were calcined at 673 K to porous nanofibers of ThO2 with an average diameter of 34 +/- 18 nm and surface area of 85 m(2) g(-1). The prepared materials were characterized by TGA-DSC, SEM, TEM, PXRD, and BET methods. (C) 2020 Elsevier B.V. All rights reserved. ER -
