Since manganese oxide nanomaterials attract wide attention in the biomedical and energy fields, understanding the inner relationship between their properties and structures is fundamental and urgently needed. However, controllable synthesis of metal oxide nanomaterials with diverse morphologies is still a persistent challenge. Herein, various anisotropic manganese oxide nanostructures from zero-dimensional (0-D) to three-dimensional (3-D) were successfully fabricated through thermal decomposition. We observed that chloride ions can assist the formation of 0-D nanooctaherals, nanocubes, and nanooctapods due to its binding capacity to the manganese ions on the nanocrystal surface. Interestingly, the procedural heating process can affect the decomposition rate of the manganese–oleate, which drives a substantial reduction in the surface free energy by sharing a common crystallographic orientation and leads to the formation of 1-D and 3-D nanostructures by oriented attachment growth. On the basis of systematic...
