... lm) of a-MnO 2 can be obtained by the reaction between MnSO 4 and (NH 4 ) 2 S 2 O 8 with the addition of AgNO 3 catalyst at RT for 1–2 days. The thin shell of this structure is composed of nanorods, ... MnO 2 is controlled by synthesis temperature. The capacitive behavior of the MnO 2 thin films with different morphologies are studied by cyclic voltammetry. The a-MnO 2 thin...
