Abstract: An improved method was presented for the synthesis of birnessite, and single-phase layered birnessite was obtained. Birnessite samples synthesized by this method were characterized by the XRD and SEM. The results indicate that the crystallinity of the birnessite synthesized by this method is increased greatly by increasing the concentration of Mn(Ⅱ) solution.

Key words: birnessite, manganese oxide, layered compound, synthesis
