摘 要：Pure SnO2 and Ce-doped（1%,4%,7%,10% in mass ratio） SnO2 powders were prepared by a simple sol-gel method.The as-prepared samples were characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,and Brunauer-Emmett-Teller（BET） specific surface area analyzers.Results showed that the 7% Ce-doped sample has a particle size of 0.1-0.3 μm with a narrow particle size distribution while the pure SnO2 was consisted of large agglomerated particles with a diameter up to several micrometers.When used as the catalyst to degrade methyl orange（MO）,the 7% Ce-doped sample showed best photocatalytic property.These properties can be attributed to the large surface area and small particle size of the 7% Ce-doped sample.
