Multi-Functional Materials Based on Cu-Doped TiO₂ Ceramic Fibers with Enhanced Pseudocapacitive Performances and Their Dielectric Characteristics.

ABSTRACT: In this work, pure TiO₂ and Cu (0.5, 1, 2%)-doped TiO₂ composites prepared by electrospinning technique followed by calcination at 900 °C, and having high pseudocapacitive and dielectric characteristics were reported. These nanocomposites were characterized by scanning electron microscopy, X-ray diffraction, and dynamic water sorption vapor measurements. The structural characterization of these nanostructures highlighted good crystallinity including only the rutile phase. The electrochemical characteristics were investigated by cyclic voltammetry and galvanostatic charge-discharge measurements, which were performed in a KOH electrolyte solution. Among the Cu-doped TiO₂ nanostructures that were prepared, the one containing 0.5% Cu exhibited superior electroc
