摘要
采用共沉淀法制备LaMgAlO(简称Me_xO_y)复合金属氧化物,以Me-xO_y为载体,采用浸渍法制备系列负载型RuO_2/Me_xO_y催化剂,应用BET、TEM、XRF和SEM对代表性样品进行表征。结果表明,实验条件下,RuO_2负载质量分数2.0%时比较合适,在气体混合物中含有氧和少量水蒸汽条件下,催化剂具有较好的催化分解N_2O稳定性。
Composite metal oxide of LaMgA10 (MexOy) was prepared by coprecipitation method in this paper. A series of supported RuO2/MexOy catalysts were prepared by impregnation method by using MexOy as support. The representative samples were characterized by BET,TEM, XRF and SEM. Experi-mental results showed that when mass fraction of RuO2 was 2.0% , catalyst had good N20 decomposition activity under experimental conditions of gas mixture containing oxygen and a small amount of water vapor.
