The microstructure characterizations and theoretical calculations reveal that surface oxygen vacancies (VO) at FeOOH NSs provide preferential deposition sites not only for CdS NCs to grow high-quality interface and form the heterostructure, but also for inert molecule adsorption. Owing to the synergistic...
. This mobility enhancement is mostly attributed to an oxygen vacancy-assisted recovery process that reduces the density of TDs by accelerating the movement of dislocations in ionic crystals under a p(O2)-controlled treatment despite an increase in the density of charged point defects. Our finding ...
Here, we design an effective and versatile strategy to construct mesoporous ABO3perovskite oxides with functionalized nanocrystal frameworks and abundant oxygen vacancy sites via a resol-assisted cationic coordinative co-assembly approach. The as-prepared oxygen vacancy-rich mesoporous LaMnO3as heterogeneous...
In this study, an oxygen vacancy (OVs) assisted Fenton-like catalyst (Mn-CuO) was designed to degrade ciprofloxacin (CIP). Results showed that Mn10CuO exhibited 3 times decomposition rate of H2O2 than that of CuO, and can make decent performances under a wide pH ranges (pH = 3.01-10.00)...
