研究了KNO 3和K2 CO 3负载的镁铝水滑石基复合氧化物催化剂对柴油机碳烟的催化燃烧性能。在空气和高纯He气中考察了催化剂与碳烟反应前后的活性。结果表明，K对催化剂活性有很大的促进作用，在静态空气气氛下，与碳烟反应后未发现失活现象。用XRD对活性相进行了表征。高活性被发现是由于K和Mg（Al）之间的相互作用，这可能会削弱Mg（Al）-O键，从而促进O物种的流动性。
KNO3or K2CO3supported Mg–Al hydrotalcite-based mixed oxide catalysts were investigated for the catalytic combustion of diesel soot. The activity of the catalysts before and after reactions with soot was conducted under the flow of air and high purity He gas. It has been found that K shows a great promotion of the catalytic activity, and deactivation was not detected after the reaction with soot in a muffle furnace in a static air atmosphere. The active phases were examined by XRD. The high activity is found to be due to an interaction between K and Mg(Al), which may weaken the Mg(Al)–O bonds, thus facilitating the mobility of the O species.
