510Mn3O4 nanoparticles (NPs) c50-250nmTEMThe morphologies of the as-prepared four shapes of Mn3O4 NPs were observed by TEM. As shown in Fig. S1, the Mn3O4 NPs display octahedral, polyhedral, flower and spinel like shapes. The results show that most of the nanoparticles exhibit regular octahedral shape and the particle size is between 50 nm and 250 nm
