Preparation of two-dimensional manganese dioxide
The feed particles are captured between the colliding grinding beads, wall, and mill stirrer in the mill chamber. Compressive and shear stress act on the bulk particles at the time of milling, which ultimately yields 2D MnO 2 nanosheets. At the time of nano-milling, some bulk particles get broken, resulting in 2D MnO 2 nanosheets.
