Abstract
The data for birnessite deposited from alkaline permanganate solutions under two- and single step potentiostatic modes are reported. The analysis of capacity vs. scan rate dependences confirmed higher contribution of interfacial recharging to capacity of the compact nanoporous deposits as compared to more resistive ramified deposits with morphology typical for natural birnessite. Two-step mode allowed us to fabricate mm-thick deposits with satisfactory adhesion and the essential content of more favorable compact birnessite.
