Disolfuri di metalli di transizione sono materiali che hanno suscitato interesse negli ultimi anni, data la loro capacità di catalizzare la reazione di evoluzione di evoluzione di ossigeno. A questo proposito in questo lavoro è stato depositato Molibdeno Disolfuro su un cristallo singolo di Au (111), in condizioni di ultra alto vuoto, mediante Physical Vapor Deposition (PVD) di Molibdeno e Zolfo. Inoltre, viene osservata l’interazione tra Molibdeno Disolfuro e Ferro o Ferro Disolfuro. Il materiale viene poi caratterizzato mediante X-ray Photoelectron Spectroscopy, Low Energy Electron Diffraction and Scanning Tunneling Microscopy.

Abstract
Transition metal disulfides are materials that have attracted interest in recent years, given their ability to catalyze the oxygen evolution reaction. In this regard, in this work Molybdenum Disulfide was deposited on a single crystal of Au (111), under ultra-high vacuum conditions, by Physical Vapor Deposition (PVD) of Molybdenum and Sulfur. Furthermore, the interaction between Molybdenum Disulfide and Iron or Iron Disulfide is observed. The material is then characterized using X-ray Photoelectron Spectroscopy, Low Energy Electron Diffraction and Scanning Tunneling Microscopy.File | Dimensione | Formato | |
