Characteristics of Samaria-Doped Ceria Prepared by Pechini Method
Acta Physica Polonica A, 2015 CeO2 ceramics doped with 20 mol.% samarium (SDC-20) were prepared through the Pechini process. The samples were calcined at 400, 700 and 1000 °C. The sintering behavior of the calcined SDC-20 powders was also investigated at 1400 °C for 6 h. Microstructural and physical properties of SDC-20 samples were characterized with X-ray diffraction, scanning ...

TiO2 synthesis by Pechini method and application in Dye Sensitized Solar Cells
Orbital: The Electronic Journal of Chemistry, 2021 Dye-sensitized solar cells (DSSC) are devices to solar energy conversion, which present low production costs and high photoelectrochemical stability. The aim of this study was to investigate the synthesis of TiO2 by Pechini methodology, using C12H28O4Ti and TiCl3 as precursors, and their application in solar cell sensitized by N719 dye.
