Summary project: The development of inexpensive and efficient electrocatalysts for oxygen and carbon cycles is highly desirable to reduce the current dependence on fossil fuels and carbon dioxide emissions. Despite enormous efforts over the years, the discovery of an efficient electrocatalyst for these processes remains a great challenge. In this proposal, we explore the thermodynamic and kinetic descriptors defining the relationships between the intrinsic properties of two-dimensional (2D) materials with bi- and tri-atomic transition metal substituents and their activities toward oxygen (O2) and carbon dioxide (CO2) reduction reactions (ORR and CO2RR). The high-throughput screening of 2D materials databases with transition metal dopants will be performed using a combination of theoretical methods: like density functional theory (DFT) + Hubbard U corrections, solvent embedded grand canonical simulations, hybrid explicit/implicit solvent models, microkinetic modelling, and emerging machine learning algorithms. We envision that the unique geometric and electronic structure of bi- and tri-atom catalysts in this study have the potential to circumvent traditional scaling relationships on transition metal catalysts, which limit their activity. At the same time, the solvent-specific theoretical methodologies to be developed will open up the possibility to study the interfacial properties and applications of electrified surfaces. This study will not only intensify the prospects of 2D materials in the field of electrocatalysis but has also the potential to broaden their scope of application in diverse fields such as electrochemical sensors, the chemical industry, anti-corrosive material synthesis, and drug design.

EuroTechPostdoc2 Programme

Within the EuroTechPostdoc2 programme, the universities of the EuroTech Universities Alliance offer seventy Marie Skłodowska-Curie fellowships to experienced high-potential researchers, in two calls for 35 fellows each. Besides giving the fellows the freedom to establish their own research lines, the programme provides exceptional training opportunities to prepare the fellows for a future as part of the new generation of scientific leaders, within and outside of academia.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement no. 899987.
