Synthesis and Structural Characterization of Metal-Doped Titanate Nanotubes Using TEM, XRD and XAS

Abstract: This work presents the synthesis and structural characterization of titanate nanoproducts, focusing on the effect induced by the presence of silver ion in different concentrations. The synthesis and chemical analysis using TEM, XRD and EDX were performed at the University of Szeged in Hungary. The XAS analysis was done at the MaxLab synchrotron facility in Lund University, Sweden. From the analysis, it is revealed that the titanate nanotubes exhibited an elongated structure before thermal treatment and were transformed into nanocrystals upon thermal treatment at 600 oC. Silver significantly promoted the conversion of titanate nanotubes into anatase phase, with the participation of new intermediates.
