Pd catalysts derived from MgAl hydrotalcite precursors were prepared by three different methods: deposition-precipitation(DP),impregnation(IM),and co-precipitation(CP),which were characterized by ICP,XRD,SEM,TEM,EDS,TPR and surface area measurement.

• 以沉积沉淀法(DP)、浸渍法(IM)和共沉淀法(CP)制备MgAl水滑石衍生氧化物负载钯催化剂,用ICP、XRD、SEM、TEM、EDS、TPR以及比表面测定等手段对催化剂进行了表征。
