Synthesis and Oxygen Storage Capacity of Two-Dimensional Ceria Nanocrystals

摘要

Shape-controlled synthesis of inorganic nanomaterials has received great attention due to their unique shape-dependent properties and their various applications in catalysis, electronics, magnetics,optics, and biomedicine. Among these nanomaterials, ultrathin two-dimensional (2D) anisotropic nanomaterials are especially attractive due to their high surface-to-volume ratio and potential quantum size effects. A variety of approaches have been developed to prepare such nanomaterials. Typical methods include vapor deposition,templated synthesis, electrochemical deposition, sol-gel processing, and solvothermal/hydrothermal treatments. Solution-phase chemical synthesis has proven particularly effective in controlling the size and morphology of the nanomaterials.
