Sep 28, 2020·UV-Raman was recorded to further study the crystal structure of as-prepared samples and the corresponding spectra were shown in Fig. 1B. Raman-active modes at 689, 619, 521 and 481 cm −1 were observed in pure Co 3 O 4, which corresponded to A 1g, F 2g and E g vibration symmetry of crystalline spinel Co 3 O 4 [].A 1g (689 cm −1) mode was assigned to the octahedral sites [CoO 6] in …
