摘要：

Sphere-like Mn3O4 nanoparticles were prepared by a simple aqueous precipitation method at 30 degrees C for 1.5 h with PEG 6000 involved. The as-prepared Mn3O4 nanoparticles extended sphere-like structures with sizes of around 80 nm. The size and shape could be manipulated by changing the species of alkali. Introduction of PEG6000 in the experiments caused the inhibition of crystal growth. The oxidiability of as-prepared Mn3O4 nanoparticles was evaluated by degradation of rhodamine B (RhB). The pH value of the reaction system was major factors to be assessed in the degradation process. After 120 minutes' reaction, the degradation efficiency can reach 61.3 %.
