2. 1. BUILDING AN X-RAY PHOTOELECTRON SPECTROSCOPY ENDSTATION FOR OPERANDO STUDIES OF CATALYTIC CO AND CO2 HYDROGENATION REACTIONS

   Author : David Degerman; Anders Nilsson; Joachim Schnadt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

   Abstract : X-ray Photoelectron Spectroscopy (XPS) provides an element-specific surface sensitive probe of the chemical composition in a system, and is consequently one of the workhorses of surface science and catalysis research. The obtained information on the chemical and physical state of the catalyst and adsorbates is essential in the endeavor to achieve a fundamental understanding how chemical reactions are facilitated by the catalyst.

4. 2. CO, CO2 and N2 hydrogenation reactions probed by operando x-ray photoelectron spectroscopy

   Author : David Degerman; Anders Nilsson; Miquel Salmeron; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Operando Catalysis; Hydrogenation reactions; High-Pressure X-Ray Photoelectron Spectroscopy; Syngas; kemisk fysik; Chemical Physics;

   Abstract : Catalytic reactions are essential for generating the chemical products required by the modern society. In particular, reactions related to clean energy storage and generation as well as fertilizer production are facilitated by catalysts. However, the processes are often insufficiently understood at a mechanistic level. READ MORE
