Journal ArticleDOI
Atomic-scale structure of single-layer MoS2 nanoclusters
Stig Helveg,Jeppe V. Lauritsen,Erik Lægsgaard,Ivan Stensgaard,Jens K. Nørskov,Clausen Bjerne Steffen,Henrik Topsøe,Flemming Besenbacher +7 more
TL;DR: The STM gives the first real space images of the shape and edge structure of single-layer MoS2 nanoparticles synthesized on Au(111), and establishes a new picture of the active edge sites of the nanoclusters.
Journal ArticleDOI
Size-dependent structure of MoS2 nanocrystals.
Jeppe V. Lauritsen,Jakob Kibsgaard,Stig Helveg,Henrik Topsøe,Bjerne S. Clausen,Erik Lægsgaard,Flemming Besenbacher +6 more
TL;DR: The novel findings suggest that good size control during the synthesis of MoS2 nanostructures may be used for the production of chemically or optically active MoS1 nanomaterials with superior performance.
Journal ArticleDOI
One-Dimensional Metallic Edge States in MoS2
Mikkel Bollinger,Jeppe V. Lauritsen,Karsten Wedel Jacobsen,Jens K. Nørskov,Stig Helveg,Flemming Besenbacher +5 more
TL;DR: By the use of density functional calculations it is shown that the edges of a two-dimensional slab of insulating MoS2 exhibit several metallic states, and these edge states can be viewed as one-dimensional conducting wires using scanning tunneling microscopy for single-layer MoS1 nanoparticles grown on a support.
Journal ArticleDOI
Location and coordination of promoter atoms in Co- and Ni-promoted MoS2-based hydrotreating catalysts
Jeppe V. Lauritsen,Jakob Kibsgaard,Georg H. Olesen,Poul Georg Moses,Berit Hinnemann,Stig Helveg,Jens K. Nørskov,Bjerne S. Clausen,Henrik Topsøe,Erik Lægsgaard,Flemming Besenbacher +10 more
TL;DR: In this paper, the authors used scanning tunneling microscopy (STM) and density functional theory (DFT) to investigate the atomic-scale structure of the active Co- or Ni-promoted MoS2 nanoclusters in hydrotreating catalysts.
Journal ArticleDOI
Atomic-scale insight into structure and morphology changes of MoS2 nanoclusters in hydrotreating catalysts
Jeppe V. Lauritsen,Mikkel Bollinger,Erik Lægsgaard,Karsten Wedel Jacobsen,Jens K. Nørskov,Clausen Bjerne Steffen,H. Topsøe,Flemming Besenbacher +7 more
TL;DR: In this article, high-resolution scanning tunneling microscopy (STM) is used in combination with density functional theory (DFT) to provide new insight into the morphology and atomic-scale structure of MoS2 nanoclusters in hydrodesulfurization (HDS) catalysts.
