Microspheres for High Performance Oxygen Evolution

Competitive Advantages

• Higher current density
• Highly stable
• Cost effective

Summary

Researchers at USF have proposed a novel hybrid catalyst with precise choice of individual components leading to excellent OER activity in alkaline medium. The hybrid Co@Ni₁₂P₅/PPy catalyst features excellent current density at low overpotential and long term stability. The proposed catalyst based on Co@Ni₁₂P₅/PPy microspheres exhibits four times higher current density than state of the art RuO₂. Employing polypyrrole as the N source in metal nitrogen active centers provides a new class of unexplored hybrid catalysts with tunable surface electronic properties for promising, large scale improvements in the oxygen evolution reactions (OER), thus enabling electrochemical water splitting at industrial scale.
