Journal ArticleDOI
NH3 adsorption on anatase-TiO2(101).
Stig Koust,Kræn C. Adamsen,Esben L. Kolsbjerg,Zhongshan Li,Bjørk Hammer,Stefan Wendt,Jeppe V. Lauritsen +6 more
TL;DR: It was found that ammonia adsorbs non-dissociatively as NH3 on regular five-fold coordinated titanium surface sites (5f-Ti) with an estimated exothermic adsorption energy of 1.2 eV for an isolated ammonia molecule.
Journal ArticleDOI
Linear hydrogen adsorbate structures on graphite induced by self-assembled molecular monolayers
Louis Nilsson,Željko Šljivančanin,Richard Balog,Wei Xu,Trolle R. Linderoth,Erik Lægsgaard,Ivan Stensgaard,Bjørk Hammer,Flemming Besenbacher,Liv Hornekær +9 more
TL;DR: In this article, a method to induce linear structures of hydrogen adsorbates on graphite by covering the surface with a self-assembled molecular monolayer of cyanuric acid and exposing it to atomic hydrogen is presented.
Journal ArticleDOI
Effects of Gas-Phase Conditions and Particle Size on the Properties of Cu(111)-Supported ZnyOx Particles Revealed by Global Optimization and Ab Initio Thermodynamics
TL;DR: The characterization of the interaction between nano or sub-nanoparticles with a support nowadays increasingly relies on computational modeling by means of the density functional theory calculation as discussed by the authors, which is a technique that has been used for many applications.
Journal ArticleDOI
Scanning Tunneling Microscopy Measurements of the Full Cycle of a Heterogeneous Asymmetric Hydrogenation Reaction on Chirally Modified Pt(111).
Vincent Demers-Carpentier,Guillaume Goubert,Federico Masini,Yi Dong,Anton M. H. Rasmussen,Bjørk Hammer,Peter H. McBreen +6 more
TL;DR: The hydrogenation of a prochiral substrate, 2,2,2-trifluoroacetophenone (TFAP), on Pt(111) was studied using room-temperature scanning tunneling microscopy (STM) measurements and some monomers display an extra protrusion compared to TFAP in dimer structures.
Journal ArticleDOI
Constructing convex energy landscapes for atomistic structure optimization
TL;DR: In this paper, a few-atom complementary energy landscape and atomic role models are proposed for atomistic structure determination based on two new concepts: atomic role model and atomic complementary landscape.
