Synthesis and shape evolution of novel cuniform-like MnO_2 in aqueous solution

摘要

In this paper, the cuniform-like MnO_2 particles were first successfully synthesized with dodecylbenzenesulfonic acid (DBSA) as surfactant in aqueous solution. The samples were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and infrared spectroscopy (IR). The possible mechanisms of the shape evolution for the formation of MnO_2 samples were discussed.
