The\u00a0NAP-XPS Workshop<\/strong> aims to present and discuss some scientific cases for studying materials, for energy and environmental applications, under in-situ and operando conditions, such as studies of catalysts, corrosion effects, reactions at interfaces, semiconductor solar cells, batteries, and biological samples. Scientists from soft X-ray photoelectron and absorption spectroscopy community are invited to attend and bring new proposals. The NAP-XPS instrumentation will be available at the Colibri beamline (100 \u2013 2000 eV) of the Sirius.<\/p>\n

Title: <\/strong>Near Ambient Pressure XPS (NAP-XPS) at the ALBA Synchrotron Light Source<\/em><\/p>\n

Abstract<\/strong>:\u00a0<\/em>The ALBA Synchrotron Light Source started operating in 2012. The CIRCE beamline (BL24), one of the seven beamlines built during the first phase, consists of two end stations in different branches dedicated to Photoemission Electron Microscopy (PEEM) and Near Ambient Pressure Photoemission spectroscopy (NAPP).<\/p>\n

In this talk we will introduce the NAPP endstation which is open to official users since November 2013. An electron energy analyzer with a differential pumping system and a set of electrostatic lenses, developed by Salmeron and Schl\u00f6gl groups and now available commercially, allows extending the standard UHV XPS (X-ray Photoelectron Spectroscopy) technique to sample pressures up to 20 millibar. As it has been shown, the surface reactivity and structure in real environments can reveal dramatic differences with respect to the solid-vacuum studies. The possibility to work with these instruments under realistic conditions and get information during the reactions or processes of interest has a great impact in different scientific topics like heterogeneous catalysis, fuel cells, photovoltaics, batteries and electrochemistry in general, corrosion, environmental science and many other fields.<\/p>\n

The NAPP end station capabilities will be described and illustrated with some examples of different research studies conducted with this instrument after just over 5 years of operation.<\/p>\n

Title: <\/strong>Atomic Quantum Clusters: a Novel Material at the Bottom of the Nanoscale. Stability of supported Cu5 in presence of oxygen.<\/em><\/p>\n

Abstract<\/strong>: Novel catalytic properties are expected from Atomic Quantum Clusters (AQC), which could lead to the development of new catalyst at the sub-nanometric scale. To evaluate their potential and real applications, studies about their stability and reactivity, associated to their support and thermodynamic conditions, become mandatory, especially through advanced in-situ characterizations methodologies. The same requirements are demanded in order to elucidate the possible catalytic mechanisms. For that, we present the in-situ study of the stability of supported Cu5 on HOPG, in presence of oxygen, employing NAP-XPS and XAS synchrotron-based techniques.<\/p>\n
