Publikováno v: APPLIED SURFACE SCIENCE

The ablation of a target, composed of a homogeneous mixture of Fe & Co metal with H3BO3 powder, produces core-shell type particles on the as-deposited coating surface. Annealing at 600 °C in air transforms the core-shell into urchin-like particles h

Autor: Martina Fracchia, Raju Edla, Paolo Ghigna, Piero Torelli, Matthias Vandichel, Lucca Braglia, Daniela Meroni, Giuseppina Cerrato, Alessandro Minguzzi, Elisabet Ahlberg

Publikováno v: The Journal of Physical Chemistry. C, Nanomaterials and Interfaces

Ambient-pressure operando soft X-ray absorption spectroscopy (soft-XAS) was applied to study the reactivity of hydroxylated SnO2 nanoparticles toward reducing gases. H2 was first used as a test case, showing that the gas phase and surface states can
