Title: Preparation and characterization of Co(Pd)CuZnLa/diatomite catalysts by modified coprecipitation method
Abstract: Diatomite-supported Co-Cu-Zn-La and Pd-Cu-Zn-La composite metal catalysts were prepared by the modified coprecipitation method of adding cationic surfactant CTAB.The prepared catalysts were characterized by SEM,TEM,XRD,FT-IR,TPR and other techniques in terms of their surface morphology,composition and reduction property.The results show that there are rich pores existed in the prepared catalytic materials,active oxide components of 4-15nm have a good dispersion with flower distribution of 200-400nm.Metallic simple substance and possible alloy can be obtained on the surfaces of the prepared catalysts after temperature-programmed reduced of hydrogen.
