Накратко на български

Оксидите на никел и желязо се анализират, за да се разбере как те ускоряват отделянето на кислород при разлагането на вода. Това помага за създаването на по-ефективни катализатори за производство на водород от възобновяеми източници, което може да намали вредните емисии.

Model Catalysts for understanding Oxygen Evolution Reaction activity

The goal of this project, Model Catalysts for Understanding Oxygen Evolution Reaction, has been the investigation of the oxygen evolution reaction (OER) employing well-defined oxide thin films and a multi-technique surface approach. The overpotential of this reaction is a limiting factor for the implementation of water splitting. Up to date, Ni-based catalysts with iron doping are the most promising ones in alkaline media. The mechanism of the reaction and the way how iron enhances the catalyst´s activity are still a matter of debate in literature. The project aimed to provide new insight into that matter. In addition, it also explored possible methods to increase the intrinsic activity of the studied catalysts. The outcome of this project may help the development of efficient OER catalysts based on abundant transition metals, which could potentially help reduce anthropogenic CO2 emissions by enabling the production of hydrogen through water splitting with renewable sources. For this reason, the project is of interest for the general public. This project focused on pursuing three scientific objectives. The first one was the identification of the most electroactive composition and orientation of ordered nickel and iron-based oxides. The second objective was to gain a fundamental understanding of the effect Fe exerts on the activity of nickel oxide, and the third objective was to enhance the catalytic OER activity by combining magnetism and electrocatalysis. In addition to the scientific objectives, the project also prioritized the training in several areas necessary for my development as an independent researcher.

Цел на проекта

Hydrogen is considered essential to reach the European Green Deal and Europe´s clean energy transition. Nowadays, most hydrogen is produced by reforming of fossil fuels. Electrochemical water electrolysis using renewable sources as energy input represents a cleaner way than reforming of fuels to create hydrogen. However, water electrolysis will only be feasible if stable, affordable and effective catalysts for oxygen evolution reaction (OER) are discovered. The research objective of this project is to explore the catalytic activity in OER of Earth abundant transition metal oxides to gain fundamental understanding on the nature of the active sites. To this effect, ordered thin films will be grown, aiming to discover the most active formulations and facets of the crystal structure. This project will be performed at the Fritz-Haber-Institut der Max-Planck-Gesellschaft (MPG), in the department of Interface Science lead by Prof. Roldán Cuenya. MPG was ranked as the third top institution according to the Nature Index 2019. I will work with Dr. Kuhlenbeck, an expert in the surface science field. Merging of his experience in growing thin films with the my background in electrochemical processes is key for the success of the project. During the two years of the project, I will be involved in the dissemination of the results to Academia and the general public through participation in conferences, publication of articles and outreach activities. An individual Career Development Plan, outlined and reviewed by Dr. Kuhlenbeck and Prof. Roldán Cuenya, will be used to monitor the research maturity obtained during the project.
