Journal ArticleDOI
Atom-Resolved Imaging of Dynamic Shape Changes in Supported Copper Nanocrystals
Poul L. Hansen,Jakob Birkedal Wagner,Stig Helveg,Jens R. Rostrup-Nielsen,Bjerne S. Clausen,Henrik Topsøe +5 more
TL;DR: In situ transmission electron microscopy is used to obtain atom-resolved images of copper nanocrystals on different supports, which are catalysts for methanol synthesis and hydrocarbon conversion processes for fuel cells.
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
In situ Mössbauer emission spectroscopy studies of unsupported and supported sulfided CoMo hydrodesulfurization catalysts: Evidence for and nature of a CoMoS phase
TL;DR: In this paper, the structure and type of phases present in sulfided alumina-supported, as well as unsupported, Co-Mo catalysts is obtained from in situ Mossbauer emission spectroscopy (MES) studies.
Journal ArticleDOI
In Situ Investigations of Structural Changes in Cu/ZnO Catalysts
TL;DR: In this article, the structure and catalytic activity of Cu/ZnO methanol synthesis catalysts have been investigated by a further developed in situ method, which combines X-ray diffraction (XRD), Xray absorption fine structure spectroscopy (XAFS), and on-line catalytic measurements by mass spectrometry.
