Mixed Ni-Fe-oxide cathodes for hydrogen production by water electrolysis

Traditional energy sources, such as fossil fuels, are rapidly being depleted. Furthermore, CO2, one of the byproducts of burning these fuels, increases environmental risk such as climate change. Therefore, novel renewable energy paths are being developed to reduce the dependency on fossil fuels. Hydrogen, a clean energy carrier, is considered to be the best alternative to the current fossil fuel energy economy. Hydrogen can be produced by electrolysis of water applying energy which split the water molecule and forms hydrogen on the cathode surface. Taking into account this information, the goal of this project is to develop new materials for the cathode, in this case particularly, nickel-iron oxides, in other to achieve a higher hydrogen production by water electrolysis at a lower cost, since the materials currently use are very expensive. In addition, these new cathodes are expected to have a better long-term stability and to perform well in the alkaline and acidic media, and seawater.
