摘要：

Higher CO conversions were achieved over Cu-Mn spinel catalysts prepared by citric acid complex method (CIT). urea homogenous coprecipitation (URE) and Pechini method (PEC) than by coprecipitation with NH3 (COP(NH3)). Higher reducibility was attained by CIT. URE and PEC than by COP(NH3). The citric acid method was a simple way to produce a catalyst with high activity. CO conversion was enhanced with a rise in calcination temperatures over the Cu-Mn spinel catalyst prepared by the citric acid method. Partial substitution of Fe or Al for Mn enhanced the catalytic activity of Cu-Mn spinel. Optimized Cu/Mn/Fe ratio was 1:1:1 in terms of catalytic activity. (C) 2004 Elsevier B.V.
