Au/3DOM La0.6Sr0.4MnO3: Highly active nanocatalysts for the oxidation of carbon monoxide and toluene

3DOM-structured La0.6Sr0.4MnO3 (LSMO) and xAu/LSMO (x = 3.4-7.9 wt%) are prepared using the polymethyl methacrylate-templating and polyvinyl alcohol-protected reduction methods, respectively. The high Oads concentration, good low-temperature reducibility, and strong Au-LSMO interaction are responsible for excellent catalytic performance of 6.4Au/LSMO for CO and toluene oxidation. 396
