Abstract

Monometallic gold and iridium, and bimetallic gold–iridium on ceria catalysts were synthesized by deposition–precipitation with urea. The activity of these ceria supported catalysts for CO oxidation was: Au–Ir ≫ Au > Ir. The bimetallic catalyst was highly active and stable during the carbon monoxide oxidation reaction, showing synergism between both metals. The catalysts were thoroughly characterized chemical and structurally. High-resolution electron microscopy coupled with energy dispersive spectroscopy and X-ray photoelectron spectroscopy showed evidences of iridium–gold intimacy. In situ infrared spectroscopy in the diffuse reflectance mode was used to investigate the reactivity of the active sites. Concentration-modulation excitation spectroscopy allowed selective identification of intermediates and ‘spectator’ species. CO chemisorbed onto iridium sites (2096, 2060 and 2012 cm−1) was found inactive, whereas carbon monoxide on metallic gold sites (Au0–CO, 2110 cm−1) exhibited reactivity for CO oxidation. In the bimetallic catalyst, new active sites (Auδ−–CO, 2095 and 2026 cm−1) together with Au0–CO species were observed, most likely produced by the isolation and stabilization of gold atoms by iridium.
