Journal ArticleDOI
Ammonia synthesis from first-principles calculations.
Karoliina Honkala,Anders Hellman,Ioannis N. Remediakis,Ashildur Logadottir,Anna Carlsson,Søren Dahl,Claus H. Christensen,Jens K. Nørskov +7 more
TL;DR: The rate of ammonia synthesis over a nanoparticle ruthenium catalyst can be calculated directly on the basis of a quantum chemical treatment of the problem using density functional theory, and offers hope for computer-based methods in the search for catalysts.
Journal ArticleDOI
The rise of hematite: origin and strategies to reduce the high onset potential for the oxygen evolution reaction
TL;DR: In this paper, a review of the appealing and challenging aspects of using hematite for photoelectrochemical (PEC) water splitting is presented, focusing on the recent efforts towards lowering the onset potential of water oxidation.
Journal ArticleDOI
Metal-polymer hybrid nanomaterials for plasmonic ultrafast hydrogen detection
Ferry Anggoro Ardy Nugroho,Iwan Darmadi,Lucy Cusinato,Arturo Susarrey-Arce,Herman Schreuders,L. J. Bannenberg,Alice Bastos da Silva Fanta,Shima Kadkhodazadeh,Jakob Birkedal Wagner,Tomasz J. Antosiewicz,Tomasz J. Antosiewicz,Anders Hellman,Vladimir P. Zhdanov,Vladimir P. Zhdanov,Bernard Dam,Christoph Langhammer +15 more
TL;DR: This work presents a plasmonic metal–polymer hybrid nanomaterial concept, where the polymer coating reduces the apparent activation energy for hydrogen transport into and out of the plAsmonic nanoparticles, while deactivation resistance is provided via a tailored tandem polymer membrane.
Journal ArticleDOI
Predicting Catalysis: Understanding Ammonia Synthesis from First-Principles Calculations
Anders Hellman,Evert Jan Baerends,Malgorzata Biczysko,Thomas Bligaard,Claus H. Christensen,David C. Clary,Søren Dahl,R. van Harrevelt,Karoliina Honkala,Hannes Jónsson,Geert-Jan Kroes,Mario Luppi,Uwe Manthe,Jens K. Nørskov,R. A. Olsen,Jan Rossmeisl,Egill Skúlason,Christofer S. Tautermann,António J. C. Varandas,Jonathan Vincent +19 more
TL;DR: The success of predicting the outcome of a catalytic reaction from first-principles calculations supports the point of view that theory will be a fully integrated tool in the search for the next generation of catalysts.
Journal ArticleDOI
The Active Phase of Palladium during Methane Oxidation.
Anders Hellman,Andrea Resta,Natalia M. Martin,Johan Gustafson,Adriana Trinchero,Per-Anders Carlsson,Olivier Balmes,Roberto Felici,R. van Rijn,Joost W. M. Frenken,Jesper N Andersen,Edvin Lundgren,Henrik Grönbeck +12 more
TL;DR: In this paper, density functional theory and in situ surface X-ray diffraction are used to identify and characterize atomic sites yielding high methane conversion and reveal facile dissociation on either under-coordinated Pd sites in PdO(101) or metallic surfaces.
