▲Fig. 2. (a-e) TEM images and (f-j) HRETM images and (k-o) EDS scans of CexZryO2 nanocomposites with the Ce:Zr molar ratios varied from 9:1 to 1:1. The corresponding SAED patterns are depicted in the insets to the respective HRETM images in (f-j).

▲Fig. 3 (a) ESR spectra of DMPO-•O2− and (b) DMPO-•OH adducted over the various CexZryO2 nanocomposites after visible light irradiation for 5 min. The insets are a comparison of DMPO-•O2− and DMPO-•OH from each catalyst under light and dark conditions.
