Journal ArticleDOI
Universal Phenomena of CO Adsorption on Gold Surfaces with Low-Coordinated Sites
Wai-Leung Yim,Tobias Nowitzki,Mandus Necke,Hanno Schnars,Patricia Nickut,Jürgen Biener,Monika M. Biener,Volkmar Zielasek,Katharina Al-Shamery,and Thorsten Klüner,Marcus Bäumer +10 more
TL;DR: In this article, temperature-programmed desorption and infrared absorption spectroscopy for a whole range of Au surfaces from nanoparticles grown on HOPG to Au(111) surfaces roughened by argon ion bombardment were performed.
Journal ArticleDOI
Formation of alkanethiolate-protected gold clusters with unprecedented core sizes in the thiolation of polymer-stabilized gold clusters
Hironori Tsunoyama,Patricia Nickut,Yuichi Negishi,Katharina Al-Shamery,Yoshiyasu Matsumoto,Tatsuya Tsukuda +5 more
TL;DR: In this paper, the authors show that the Au:SR (R = organic group) clusters with a high tolerance to thiol etching can be systematically synthesized by first populating precursory Au clusters in a poly(N-vinyl-2-pyrrolidone) matrix with subsequent thiolation of the preformed Au clusters.
Journal ArticleDOI
Low temperature dissociation of CO at reactive step sites of Pd(112)
TL;DR: In this article, the role of step sites in catalysis in a defined way without having to deal with further complications such as size effects and nanoparticle-support interaction was studied.
Journal ArticleDOI
Design of a UHV-compatible rf plasma source and its application to self-assembled layers of CoPt3 nanoparticles
Bernhard Gehl,U. Leist,Vesna Aleksandrovic,Patricia Nickut,Volkmar Zielasek,Horst Weller,Katharina Al-Shamery,Marcus Bäumer +7 more
TL;DR: In this paper, a compact, versatile, and simple rf plasma source with capacitive coupling compatible to ultra-high vacuum (UHV) requirements was designed and built to allow sequences of sample surface modification in plasma and surface preparation and analysis in vacuum without breaking the vacuum.
Journal ArticleDOI
Au deposits on graphite: On the nature of high temperature desorption peaks in CO thermal desorption spectra
Tobias Nowitzki,Patricia Nickut,C. Deiter,J. Wollschläger,Katharina Al-Shamery,Marcus Bäumer +5 more
TL;DR: In this article, the authors have studied Au deposits on graphite in order to elucidate the nature of these desorption peaks in more detail, and they conclude that these peaks are defect-related and connected with under-coordinated Au atoms that are lost for the most part upon annealing.
