Hierarchical nanostructures of hydrated α-manganese dioxide (MnO2) are prepared and their kinetics properties are characterized using scanning electrochemical microscopy (SECM). The SECM measurements are focused on the feedback mode approach curve to extract the effective heterogeneous charge transf...
