Bifunctional Electrocatalysts for the Oxygen Reduction Reaction (ORR) and Oxygen Evolution Reaction (OER) in Hydrogen–Oxygen Fuel Cells

Among various sustainable developmental strategies and technologies adopted to address environmental issues associated with fossil fuels, fuel cells are in the limelight as primary energy conversion devices. Fuel cells feature a bifunctional electrode that facilitates the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). However,

Neutral and alkaline chemical environment dependent synthesis of Mn3O4 for oxygen evolution reaction (OER)

Materials Chemistry and Physics, 2020
Abstract Co-precipitation assisted hydrothermal synthesis was employed to prepare Mn3O4 electrocatalysts for efficient electrochemical water oxidation. Tetragonal structure of high crystalline and pure phase Mn3O4 nanostructures was confirmed by X-ray diffraction (XRD) spectra. Physical characteristics such as vibration, optical and morphology of the

Mesoporous oxides as efficient catalysts for the electrocatalytic oxygen evolution reaction (OER)

2016
Hydrogen is considered an important energy carrier and feedstock for industrial applications. The generation of hydrogen can be realised by electrocatalytic water splitting. However, the efficiency of water electrolysers is limited by the slow kinetics of oxygen evolution reaction (OER).

Mixed Metal Oxide Catalyst Development for the Oxygen Evolution Reaction (OER) in Acid

ECS Meeting Abstracts
Owing to the highly oxidative and corrosive environment at the anode of proton exchange membrane water electrolysers (PEM-WE), IrOx materials are the only commercially relevant catalysts. Driven by the high costs, scarcity and instability of the iridium market, strategies to reduce the iridium content without compromising anode performance represent
