Gas-induced selective re-orientation of Au–Cu nanoparticles on TiO 2 (110)
Résumé
Au–Cu bimetallic nanoparticles (NPs) grown on TiO 2 (110) have been followed in situ using grazing incidence X-ray diffraction and X-ray photoemission spectroscopy from their synthesis to their exposure to a CO/O 2 mixture at low pressure ( P < 10 −5 mbar) and at different temperatures (300 K–470 K).
