Silicone nanofilament supported nickel oxide: a new concept for oxygen evolution catalysts in water electrolyzers


Meseck, Georg R; Fabbri, Emiliana; Schmidt, Thomas J; Seeger, Stefan (2015). Silicone nanofilament supported nickel oxide: a new concept for oxygen evolution catalysts in water electrolyzers. Advanced Materials Interfaces, 2(12):online.

Abstract

So far, the use of renewable energies has been limited since specifically wind and solar energies are subject to daily and seasonal fluctuations. Means for the efficient storage of energy are hence required to better exploit these resources. One approach that is intensively investigated is the production of hydrogen using alkaline water electrolyzers.The idea of storing electrical
energy as hydrogen is especially elegant because the reaction can be reverted to electricity in fuel cells to close the circle toward a sustainable hydrogen economy. An obstacle is however the high overpotential that is typically associated with the oxygen evolution reaction (OER) that takes place at the anode side. As a result, much effort has been spent to fi nd materials with better kinetics.
