Electrochemical deposition and behavior of mixed-valent molybdenum oxide film at glassy carbon and ITO electrodes

▸ The effect of solution composition on the MoO3 formation was investigated. ▸ The mixed-valent oxide species was produced electrochemically on a GCE and ITO ▸ XPS studies confirmed that the deposit contains both Mo(V) and Mo(VI). ▸ The MoO3 films were exhibited unique catalytic activity towards nitrite oxidation.
