摘要：
Mesostructured alumina-carbon composites with different Al/C ratio were synthesized by soft template approach. Copper oxide active phase was deposited by incipient wetness technique. The composites and the catalysts were characterized by TG, XRD, low temperature N-2-adsorption, TEM, XPS. The catalytic behaviour in NO reduction with CO in 25-300 degrees C was studied. The presence of metal ions in various oxidation states on the surface provides active centres for the adsorption of NO and CO and consequently their reaction.
