As-formed nanosheets will further aggregate into hierarchical spheres at appropriate conditions, driven by the minimization of interfacial energy 27 28 29 , The different properties of the used organic solvents, such as polarity, viscosity and coordinating ability may be significant in the shape control of the precursor.
