Interest in the fabrication of inorganic particles with controlled size and shape is driven by their potential unique and tunable physical properties and the desire to engineer advanced bulk materials from micro- or nano-scale building blocks [1, 2]. CeO2 is a technologically important rare earth material because of its wide applications as fast ion conductors, oxygen storage capacitors, catalysts, UV blockers, polishing materials, and optical displays [3, 4, 5, 6, 7]. Both single crystal and polycrystalline ceria micro- or nano-structures with different shapes, such as nanopolyhedra , nanocubes , nanospheres , nanorods/nanowires [11, 12, 13, 14, 15, 16], core-shell nanowires , nanotubes [18, 19], and triangular microplates  have been synthesized by us and other research groups in recent years. It is found that the properties and applications of micro- or nano-materials are related to their morphologies and sizes. For example, Guo et al.  synthesized...
