“…PL spectra, as shown in Figure 8 , were employed to investigate the recombination efficiency of photoinduced electrons and holes, where a lower recombination rate is characterized by a lower PL intensity [ 17 , 67 ]. It can be found that all PL spectra show strong blue emission peaks centered at 430–490 nm, which is associated with the defect levels localized between the Ce 4f and O 2p bands [ 68 , 69 , 70 , 71 ].…”

Oxygen vacancies (OVs) have critical effects on the photoelectric characterizations and photocatalytic activity of nanoceria, but the contributions of surface OVs on the promoted photocatalytic properties are not clear yet. In this work, we synthesized ceria nanopolyhedron (P-CeO2), ceria nanocube (C-CeO2) and ceria nanorod (R-CeO2), respectively, and annealed them at 600 °C in air, 30%, 60% or pure H2. After annealing, the surface OVs concentration of ceria elevates with the rising of H2 concentration. Photocatalytic activity of annealed ceria is promoted with the increasing of surface OVs, the methylene blue photodegradation ratio with pure hydrogen annealed of P-CeO2, C-CeO2 or R-CeO2 is 93.82%, 85.15% and 90.09%, respectively. Band gap of annealed ceria expands first and then tends to narrow slightly with the rising of surface OVs, while the valence band (VB) and conductive band (CB) of annealed ceria changed slightly. Both of photoluminescence spectra and photocurrent results indicate that the separation efficiency of photoinduced electron-hole pairs is significantly enhanced with the increasing of the surface OVs concentration. The notable weakened recombination of photogenerated carrier is suggested to attribute a momentous contribution on the enhanced photocatalytic activity of ceria which contains surface OVs.

“…It was proposed that the reason for the observed effect was related to the presence of teichoic acid in the peptidoglycan layer of gram-negative bacteria that interact with CeO 2 NPs. Recent examinations focus on the antimicrobial activity of Zr doped CeO 2 NPs with different concentrations of Zr synthesized by precipitation method [269]. The varying ratio of Zr impregnated CeO 2 NPs (5 to 15%) did not greatly influence the moderate antimicrobial activity against S. aureus, E. coli, P. aeruginosa, S. faecalis, B. subtilis and P. vulgaris of the modified NPs.…”
