Project Summary

Electrolysis is one of the best known and simplest methods used for the production of pure hydrogen, both on a small and large scale, starting from water, that is, from an extremely abundant primary source.

The objective of this dissertation thesis is to build on the prospective results of the SPL-HTC RI, predominantly in the area of novel catalysts for the oxygen evolution reaction. Magnetron sputtered thin-film catalysts, typically with a structure of Ni,Co,Fe/porous sublayer will be studied with emphasis on the stability and activity dependence on morphology and defect density. Layers of various compositions and morphologies will be prepared with the goal of identifying the ideal structural parameters in terms of both durability and activity. Wide arsenal of analytical methods will be available, ranging from electrochemical testing through X-ray photoelectron spectroscopy to electron microscopy. A great focus will be laid on the operando variants of those methods.

Total budget for the implementation of the action: EUR 180.000
