The galvanic exchange between Mn2 +ions and electrodeposited porous PbO2was studied to produce a porous oxide whose lower conductivity prevented its direct oxygen bubble-templated anodic deposition.

Abstract

The galvanic exchange between Mn2 +ions and electrodeposited porous PbO2was studied to produce a porous oxide whose lower conductivity prevented its direct oxygen bubble-templated anodic deposition. Immersion of PbO2layers in acid acetate solutions of Mn2 +led to the formation of amorphous MnOxshell onto PbO2. Due to its amorphous nature, MnOxcould not be proved to be MnO2by XRD. However, MnOxwas cathodically stripped at the same potential as MnO2. The deposition of the MnOxshell onto PbO2enhanced the capacity of the porous electrodes.
