Nanoflower-like architectures represent a unique type of nanomaterials in which thin 2D nanosheets are self-organised into interconnected structures. Lack of restacking between nanosheets and significant internal porosity are the particular advantages of such nanoscale architectures. A general method for the preparation of nanoflowers of a range of oxides (e.g., FeTiO3 , TiO2 , Mn2 O3 ) through a two-step procedure of ball milling and subsequent hydrothermal treatment is outlined. Importantly, the synthetic method is valid not only for a single oxide, but is extendable to a family of oxide materials. It is established that the formation of the nanoflowers from ball-milled powders follows a d..
