Why this paper? By analysing the nature of chemical bonding at the metal/oxide interface, we developed a simple parameter, the Me–Me alloy formation energy, acting as a descriptor for the strength of the interaction between metal substrates and reduced oxide monolayers, and having predictive power towards the conditions under which an overlayer is stable.

Why this paper? In this work, we demonstrate how the power of ab initio thermodynamics can be applied best. We construct phase diagrams of the atomically dispersed platinum in PtOx clusters on various ceria surfaces under a range of experimentally relevant conditions, and show how these can be used to predict dynamic restructuring of atomically dispersed platinum catalysts.
- D. Palagin, V. L. Sushkevich, and J. A. van Bokhoven, “Water Molecules Facilitate Hydrogen Release in Anaerobic Oxidation of Methane to Methanol over Cu/Mordenite”, ACS Catal. 9, 10365 (2019).
Why this paper? In this work, we combine DFT and MD simulations to identify an elusive short-lived [Cu–H] intermediate species and show how it plays a crucial role in the mechanism of the anaerobic methane to methanol conversion reaction.
- V. L. Sushkevich, D. Palagin, M. Ranocchiari, and J. A. van Bokhoven, “Selective anaerobic oxidation of methane enables direct synthesis of methanol”, Science 356, 523 (2017).
Why this paper? A classical “What if?” question lead to a breakthrough idea of using water as a cheap and efficient three-in-one agent to oxidize the material, stabilize intermediates, and release products.
- C. Panosetti, K. Krautgasser, D. Palagin, K. Reuter, and R. J. Maurer, “Global Materials Structure Search with Chemically-Motivated Coordinates”, Nano Letters 15, 8044 (2015)
Why this paper? By thinking in terms of chemistry, not mathematics, we proposed an efficient global structure search method, tailored to identify chemically relevant structures.
