Length effect of ceria nanorod on its oxygen vacancy formation and photocatalytic property
Ceria nanorods (NRs) with an average length of 23, 73, 115, 131, and 192 nm were synthesized separately by a facile hydrothermal method and then were roasted at 600 °C in air, 50% H 2 , and pure H 2 to generate various concentrations of surface oxygen vacancies (OVs). OVs concentration in ceria latt...
