摘要

Oxygen vacancy (V-O) is one of the most common defects in metal oxides (MOs), which endow the MOs with many unique physiochemical properties. Even though V-O engineering has been applied in photo(electro)catalysis, there are still significant challenges in the understanding of the formation, structure, and property of V-O. The V-O can be produced by treating MOs under low oxygen atmosphere or in vacuum ruled by the equilibrium of V-O formation, while other types of defects can also be generated simultaneously. Identifying and distinguishing the formation and function of Vo remain highly challenging, thus the scrutiny of defect formation energy and structure of V-O is significant in V-O research. This review critically revisits the electronic property and structure changes of MOs upon the generation of Vo. It not only provides clues to detect V-O, but also specifies the role of V-O in a particular material system considering its drastic influence on light harvesting, conductivity, energy level, surface adsorption, and others. The review also presents a perspective on the future research directions toward rational control of the key aspects of Vo in MOs, namely its formation, characterization, and function, for solar energy conversion.
