Abstract :
A AuLa2(OH)9 coprecipitate calcined in air at temperatures below 450 K showed surprisingly high catalytic activity for CO oxidation, 100% conversion at a temperature as low as 193 K, when it was reduced in a N2 stream containing H2 or CO at 373 K. The reduction treatment transformed Au(OH)3 species interacting with the La(OH)3 support into Au0 clusters smaller than 1.8 nm in diameters.
