Description 175-185
Existing work describes the synthesis of pristine ZnO and Er-doped ZnO by mechanochemical method and evaluation of the
photocatalytic activity synthesized samples towards photochemical degradation of Thymol Blue dye. The right calcination
temperature has been gained from TGA-DTA analysis. FTIR results show the formation metal oxides from their respective
precursors upon calcinations. XRD data obtained for ZnO and Er-ZnO clearly suggest the hexagonal wurtzite crystallite
structures. FE-SEM images established nanocrystalline morphology. The elemental pureness of these samples is confirmed by
EDX study. The optical band gaps are determined from UV-Visible spectroscopic studies. PL spectra are used to explore the
additional information about optical properties of said photocatalysts. The comparative studies of photocatalytic activities of
these materials towards degradation of Thymol Blue dye is carried out with respect to involved operational parameters. The
possible degradation intermediates and products are also illustrated with HPLC & HRMS techniques.
