Shape Evolution of Single-Crystalline Mn₂O₃ Using a Solvothermal Approach

A new and facile route was developed to manipulate the growth of hierarchically ordered Mn₂O₃ architectures via a solvothermal approach. Various solvents are employed to control the product morphologies and structures. Mn₂O₃ with unique cuboctahedral, truncated-octahedral, and octahedral shapes are obtained, and a possible formation mechanism is proposed.
