Manganese (IV) oxide (MnO2) nano-sheets were synthesized using tetramethylamine, H2O2, and MnCl2·4H2O and used in suspension for removal of methylene blue (MB). Up to 95% removal was achieved for MB concentrations less than 500mg/L. The adsorption data fitted better with the Freundlich isotherm model than the Langmuir model, indicating a heterogeneous adsorption of MB on MnO2nano-sheets. The maximum adsorption capacity of MnO2nano-sheets was approximately 4300mg/g, which is the highest yet reported. Suspensions of MnO2nano-sheets aggregated as...
