From crystal structures to functional devices: a review of mixed metal oxides in energy conversion and sensing systems
摘要
Mixed oxides, due to their highly tunable physical and chemical properties, play a key role in a wide range of advanced technologies such as catalysis, optoelectronics, energy generation and storage. To achieve optimal performance of these materials, a deep understanding of the link between their chemical composition, atomic arrangement and crystal lattice topology is essential. The current survey provides a comprehensive review of the structure and lattice of mixed oxides and emphasizes the importance of accurately identifying and analyzing the atomic structures to elucidate their relationship with the ultimate performance of the materials. Advanced structural analysis methods are used to elucidate structural details, defects and atomic connections at different scales. The effects of various cations, oxidation states and synthesis conditions on the formation of specific phases and changes in lattice parameters are discussed in detail. The crucial role of the bonding Lattices in determining the fundamental electronic, optical and catalytic properties of these materials is also carefully explored. The ultimate goal of this review is to advance the fundamental knowledge of mixed oxides and provide practical approaches for the design and synthesis of new materials with targeted properties and superior performance in future applications.
