Recent research trends have seen a rise in the interest in Transition Metal Oxides (TMO's) as catalysts for the Oxygen Evolution Reaction (OER). In particular, the use of inexpensive mixed TMO's such as Fe and Ni has gained much attention. While some techniques, such as electrodeposition, are widely investigated, reports into the fabrication of Fe, Ni/Fe and Ni oxides for the OER by alternative methods are sparse. To our knowledge, a study involving hydrothermal synthesis to produce all three of the aforementioned catalysts for the OER has yet to be undertaken. Additionally, the use of high surface area electrode supports to enhance the properties of the OER materials is very popular at present. Currently, industrial alkaline electrolysis uses Ni foam as an electrode due to its high porosity, three dimensional structure and low cost. Herein, the hydrothermal synthesis of nanoscale Fe, Ni/Fe and Ni oxide particles is …    «
