Sm3+ Doping-Induced Suppression of Ce3+ 4f1 Trap States in CeO2 for Efficient Photocatalytic Overall Water Splitting.
Defect engineering and electronic structure modification are central to the development of efficient metal oxide photocatalysts for overall water splitting. However, the role of specific electronic trap states that govern charge carrier dynamics remains incompletely understood. Herein, we report a lanthanide-assisted s...
