A Novel Electrochemical Method for Preparation of Thin Films of Layered Manganese Oxides

Abstract

Thin films of layered manganese oxides with alkylammonium and alkali-metal ions in the interlayer were formed on a platinum electrode by a one-step electrochemical route. The interlayer distance was determined by the size of the electrolyte cations used.

Electrochemical synthesis of birnessite-type layered manganese oxides for rechargeable lithium batteries

“…Recently, a new electrochemical method was developed at Yamaguchi University to synthesize birnessite-type layered MnO 2 intercalated with organic molecules such as alkylammonium ions [14,15] and polycations [16]. The electrodeposition process involves a potentiostatic oxidation of aqueous Mn 2+ ions in the presence of a small amount of organic molecules.…”

Cathodic Synthesis of Birnessite Films for Pseudocapacitor Application

“…Such a structure can be considered as an assembly of "surfaces", which may offer an increase in the number of electrochemically active sites per unit volume. Birnessites had been synthesized exclusively in a powder form through various chemical approaches including oxidation of Mn 2+ (4), reduction of MnO 4 - (5), and mixing of MnO 4 -and Mn 2+ (6,7) until we discovered a facile electrochemical route to build it as a thin film (8). Our process consists of potentiostatic oxidation of aqueous Mn 2+ ions in the presence of foreign cations to be accommodated between MnO 2 layers.…”

A Biosensor Composed of Glucose Oxidase‐Containing Liposomes and MnO2‐Based Layered Nanocomposite

“…In 2004, Nakayama et al presented a facile electrochemical route to synthesize birnessite-type multilayered manganese oxides intercalated with alkylammonium ions, as a thin film [11]. The process involves potentiostatic oxidation of aqueous Mn 2þ ions in the presence of guest cations.…”
