Journal ArticleDOI
Determination of the Particle Size, Available Surface Area, and Nature of Exposed Sites for Silica-Alumina-Supported Pd Nanoparticles: A Multitechnical Approach
Giovanni Agostini,Riccardo Pellegrini,G. Leofanti,Luca Bertinetti,Serena Bertarione,Elena Groppo,A. Zecchina,Carlo Lamberti +7 more
TL;DR: In this article, the effects of activation temperature and activation atmosphere (air or H2) on the particle size distribution, the fraction, and the type of exposed surface sites of Pd nanoparticles supported on a high surface area SiO2−Al2O3 (SA) support are investigated.
Journal ArticleDOI
In situ formation of hydrides and carbides in palladium catalyst: When XANES is better than EXAFS and XRD
Aram L. Bugaev,Aram L. Bugaev,Alexander A. Guda,Andrea Lazzarini,Kirill A. Lomachenko,Elena Groppo,Riccardo Pellegrini,Andrea Piovano,Hermann Emerich,Alexander V. Soldatov,Lusegen A. Bugaev,Vladimir Dmitriev,Jeroen A. van Bokhoven,Jeroen A. van Bokhoven,Carlo Lamberti,Carlo Lamberti +15 more
TL;DR: In this article, the structural evolution of an industrial Pd/C catalyst in the presence of hydrogen and acetylene was determined by means of in situ X-ray absorption spectroscopy and Xray powder diffraction.
Journal ArticleDOI
A comprehensive approach to investigate the structural and surface properties of activated carbons and related Pd-based catalysts
Andrea Lazzarini,Andrea Piovano,Riccardo Pellegrini,Giuseppe Leofanti,Giovanni Agostini,Svemir Rudić,Michele R. Chierotti,Roberto Gobetto,Alfio Battiato,Giuseppe Spoto,Adriano Zecchina,Carlo Lamberti,Carlo Lamberti,Elena Groppo +13 more
TL;DR: In this paper, a multi-technique approach was proposed to characterize both carbons and catalysts at the micro- and nanoscale, including the texture, morphology, and surface properties of carbon-supported catalysts.
Journal ArticleDOI
Core–Shell Structure of Palladium Hydride Nanoparticles Revealed by Combined X-ray Absorption Spectroscopy and X-ray Diffraction
Aram L. Bugaev,Aram L. Bugaev,Alexander A. Guda,Kirill A. Lomachenko,Kirill A. Lomachenko,V. V. Shapovalov,Andrea Lazzarini,Andrea Lazzarini,Jenny G. Vitillo,Lusegen A. Bugaev,Elena Groppo,Riccardo Pellegrini,Alexander V. Soldatov,Jeroen A. van Bokhoven,Jeroen A. van Bokhoven,Carlo Lamberti,Carlo Lamberti +16 more
TL;DR: In this paper, an in situ, temperature and H2 pressure-dependent, characterization of (2.6 ± 0.4) nm palladium nanoparticles supported on active carbon during the process of hydride phase formation is reported.
Journal ArticleDOI
Graphitization of Activated Carbons: A Molecular-level Investigation by INS, DRIFT, XRD and Raman Techniques
Andrea Lazzarini,Andrea Piovano,Riccardo Pellegrini,Giovanni Agostini,Svemir Rudić,Carlo Lamberti,Carlo Lamberti,Elena Groppo +7 more
TL;DR: In this paper, the effect of graphitization treatment on phyisico-chemical properties of an activated carbon has been studied by means of multi-technical approach, involving inelastic neutron scattering and DRIFT spectroscopy.
