| Abstract Scope |
With the field of nanomaterials rapidly expanding, the desire to find more cost-effective and safer ways to synthesis materials is rising. Due to their found use in energy storage, molecular absorption, and drug delivery, manganese oxide nanomaterials, and their synthesis, have been explored in recent years. Herein we take manganese precursors of varying structure (binary and ternary, layered and non-layered) and combine them with a quaternary ammonium hydroxide solution, to convert them into 2D, well-stacked flakes of crystalline, hexagonal birnessite (δ-MnO2). This method is a bottom up, one-pot, synthesis method which is cheaper and more easily scalable than the top-down methods used currently to form birnessite. When varying the precursor, the resulting material is the same. However, when varying the quaternary ammonium hydroxide solution, we can alter the interlayer spacing and obtain almost the same material overall using a less hazardous solvent. |
