title: Two-dimensional nanosheets associated with one-dimensional single-crystalline nanorods self-assembled into three-dimensional flower-like Mn₃O₄ hierarchical architectures.
abstract: Three-dimensional (3D) flower-like hausmannite architectures of Mn3O4 with uniform morphology have been successfully synthesized by a novel chemical reaction route using cetyltrimethylammonium bromide as the template. Micro/nanostructures of the as-synthesized 3D flower-like Mn3O4 architectures were investigated in detail by a series of analytical techniques. The geometrical shape of 3D flower-like Mn3O4 architectures is structurally perfect, and they are produced with diameters in the range of several hundred nanometers to a few micrometers. Experimental results indicate that two-dimensional nanosheets associated with one-dimensional single-crystalline nanorods self-assembled into three-dimensional flower-like Mn3O4 architectures. The single-crystalline Mn3O4 nanorods are a few hundred nanometers long and several tens of nanometers wide. Different dimensional systems, such as two-dimensional nanosheets, one-dimensional nanorods, and three-dimensional nanoflowers, could provide different building blocks to constitute nanostructured materials. These specific building blocks, which constituted the complex hierarchical architectures with nanostructural features, may offer exciting opportunities for both fundamental research and technological applications.
