Abstract

The future supply of fossil fuels is surrounded by uncertainty. As our fossil fuel reserves continue to diminish, it is necessary to find sustainable energy resources. A promising alternative is water splitting. However, water splitting remains a difficult task due to lack of efficient and low cost methods. We report the preparation of a Co-Fe-P catalyst that has both oxygen and hydrogen evolution activity. The catalyst was prepared using controlled potential coulometry and deposition time and electrolyte bath concentrations were tuned in order to optimize deposition conditions. Previously, we had reported a Co-P catalyst with excellent OER and HER activity. The incorporation of Fe into Co-P in an appropriate amount shifted the onset of OER by 0.05 V, and the onset of HER by 0.02 V . Possible new substrates and limitations of the catalyst are also discussed.
