摘要：

Copper iron composite oxides (CuO/Fe2O3) and copper cobalt composite oxides (CuO/Co3O4) for the catalytic reduction of NO with GO at low temperature were prepared by co-precipitation. The catalytic activity and thermal stability of the catalysts were evaluated by a microreactor-GC system. The 100% conversion temperatures of NO are 80 degrees C for CuO/Fe2O3 and 90 degrees C for CuO/Co3O4. The catalysts possess high catalytic activity and favorable thermal stability for NO reduction with GO in a wide temperature range and long time range. A systematic study of the molar ratios of the reactants, the volume of NaOH; aging time, and calcination temperature/time was carried out to investigate the influence preparation conditions on the catalytic activity of the catalysts.
