摘要：A series of mesoporous PdCeOx solid solution with high specific area was successfully fabricated through a facile coprecipitation and low-temperature calcination strategy. The resulting materials possessed excellent catalytic activities for CO oxidation. The complete CO conversion could be achieved at as low as 20 degrees C. The doping of palladium increased the concentration of structural oxygen vacancy which is beneficial for the CO oxidation reaction process. The CO oxidation reaction mechanism over PdCeOx solid solution was proved through in situ DRIFTS analysis.
