Tuning the Aspect Ratio of Ceria Nanorods and Nanodumbbells by a Face-Specific Growth and Dissolution Process

Fine tuning of the axial ratio of ceria nanorods by a time-dependent, face-specific growth and dissolution process has been demonstrated for the first time. Nearly monodisperse ceria nanorods can be synthesized by thermal decomposition of a ceria complex in the presence of only one type of surfactant (oleic acid). Strikingly, we find that the ceria [...]
