Abstract

Energy dispersive EXAFS (EDE) and diffuse reflectance infrared spectroscopy (DRIFTS) are combined synchronously at high time resolution (17 Hz) to probe how NO_(g) reacts with γ-Al₂O₃ supported, metallic Rh nanoparticles of an average 11 Å diameter; a bent nitrosyl species is considered to be the key to the formation of N₂O.
