Progress in Development of Nanostructured Manganese Oxide as Catalyst for Oxygen Reduction and Evolution Reaction

The rise in energy consumption is largely driven by the growth of population. supply to meet that demand can be fulfilled slowly introducing from renewable resources. fluctuating nature production (i.e., affected weather such as wind, sun light, etc.), necessitates increasing developing electricity storage systems. Reliable system will also play immense roles support activities related internet things. In past decades, metal-air batteries have attracted great attention and interest for their high theoretical capacity, environmental friendliness, low cost. However, one main challenges faced slow rate oxygen reduction reaction (ORR) evolution (OER) affects charging discharging performance. Various types nanostructure manganese oxide with specific surface area excellent catalytic properties been synthesized studied. This review provides a discussion recent developments performance reactions alkaline media. It includes experimental work oxide, but fundamental understanding ORR OER. A brief on electrocatalyst kinetics including measurement criteria OER included. Finally, recently reported catalysts are discussed.
