摘要
Eighteen Ce0.76Zr0.24O2 samples have been prepared by different procedures and characterised by N-2 adsorption at -196 degrees C, XRD, Raman spectroscopy, H-2-TPR and XPS. The catalytic activity for soot combustion depends both on the BET surface area and on the Ce/Zr atomic surface ratio, which strongly depends on the preparation procedure.
