Effect of iron content on electrodeposited Fe-MnOx catalysts for water oxidation
MetadataShow full item record
MnOx materials are earth-abundant and known to be efficient catalysts for the water oxidation reaction (WOR). I present the exploration of an optimal method of cathodically electrodepositing MnOx catalysts on an FTO substrate, allowing for quick synthesis and a homogeneous coverage of the substrate. I then study WOR activity of the MnOx catalyst with varying amounts of Fe in the structure. The catalyst structure was probed using XPS for elemental analysis, FESEM to study the morphology, and a Kelvin probe for exploration of the work function, and observations are discussed.
