Abstract
CeO2 nanocubes (and nanorods) enclosed by six {200} planes with controlled sizes have been prepared through a facile one-pot method. The nanocubes have a strong tendency to assemble into 2D and 3D arrays with regular patterns on a substrate, which is probably driven by the dipole−dipole interaction of polar {200} planes. The possible formation mechanism of the nanocubes has been put forward as the oriented aggregation mediated precursor growth. It is possible to use the synthesized nanocubes as building blocks to achieve {200}-perfect-oriented monolayers or thickness-controlled films and to apply the preparative method in the incorporation of heterogeneous atoms or nanoparticles for semiconductor doping or heterogeneous nanostructures.Keywords
