Journal ArticleDOI
Modeling the Electrochemical Hydrogen Oxidation and Evolution Reactions on the Basis of Density Functional Theory Calculations
Egill Skúlason,Vladimir Tripkovic,Mårten E. Björketun,Sigridur Gudmundsdottir,Gustav Karlberg,Jan Rossmeisl,Thomas Bligaard,Hannes Jónsson,Jens K. Nørskov +8 more
TL;DR: In this article, a detailed model consisting of a negatively charged Pt(111) slab and solvated protons in up to three water bilayers is considered and reaction energies and activation barriers are determined by using a newly developed computational scheme where the potential can be kept constant during a charge transfer reaction.
Journal ArticleDOI
Bioinspired molecular co-catalysts bonded to a silicon photocathode for solar hydrogen evolution
Yidong Hou,Billie Abrams,Peter Christian Kjærgaard Vesborg,Mårten E. Björketun,Konrad Herbst,Lone Bech,Alessandro M. Setti,Christian Danvad Damsgaard,Thomas Garm Pedersen,Ole Hansen,Jan Rossmeisl,Søren Dahl,Jens K. Nørskov,Jens K. Nørskov,Ib Chorkendorff +14 more
TL;DR: It is shown that bioinspired molecular clusters based on molybdenum and sulphur evolve hydrogen at rates comparable to that of platinum, and the current densities at the reversible potential match the requirement of a photoelectrochemical hydrogen production system with a solar-to-hydrogen efficiency in excess of 10%.
Journal ArticleDOI
Universal transition state scaling relations for (de)hydrogenation over transition metals
Sheng-Guang Wang,Vivien Gabriele Petzold,Vladimir Tripkovic,Jesper Kleis,Jakob Geelmuyden Howalt,Egill Skúlason,Egill Skúlason,Eva M. Fernández,Britt Hvolbæk,Glenn Jones,Anja Toftelund,Hanne Falsig,Mårten E. Björketun,Felix Studt,Frank Abild-Pedersen,Jan Rossmeisl,Jens K. Nørskov,Jens K. Nørskov,Thomas Bligaard +18 more
TL;DR: With a suitable choice of reference systems the transition state scaling relations form a universality class that can be approximated with one single linear relation describing the entire range of reactions over all types of surfaces and nanoclusters.
Journal ArticleDOI
Modeling the electrified solid-liquid interface
TL;DR: In this paper, a detailed model based on density functional theory calculations is presented of the charged solid-electrolyte interface, where the interface capacitance is well described and how the work function can be related directly to the potential scale of the normal hydrogen electrode.
Journal ArticleDOI
Electrochemical CO2 and CO reduction on metal-functionalized porphyrin-like graphene
Vladimir Tripkovic,Marco Vanin,Mohammadreza Karamad,Mårten E. Björketun,Karsten Wedel Jacobsen,Kristian Sommer Thygesen,Jan Rossmeisl +6 more
TL;DR: In this article, the porphyrin-like metal-functionalized graphene structures have been investigated as possible catalysts for CO2 and CO reduction to methane or methanol.
