The Controlled Synthesis of Birnessite Nanoflowers via H₂O₂ Reducing KMnO₄ For Efficient Adsorption and Photooxidation Activity.

ABSTRACT: Birnessite nanoflowers composed of layers have been proven to be the strongest adsorbent and oxidant in the surface environment. However, the current synthesis methods of birnessite nanoflowers are suffering from long reaction time and high reaction temperature. Based on these, this paper explores a new method for the rapid and controlled synthesis of layered manganese oxides. The method relies on the molar ratios of KMnO₄ and H₂O₂ redox reacting species to drive the production of birnessite nanoflowers under acidic conditions. The molar ratios of KMnO₄ and H₂O₂ are the key to the crystal structure of the as-prepared. It was found that when the molar ratios of KMnO₄ and H₂O₂ is from 1:1.25 to
