Zirconia-doped ceria (Ce1-xZrxO2) is a complex material and an important component of catalysts used in automotive exhaust gas converters. The exact role of pure and Zr-doped ceria to reduce the emission of toxic pollutants such as nitrogen oxides NOx (NO2, NO, N2O) in automobile catalytic converters is not clear. Understanding the details of NOx chemistry on Ce1-xZrxO2 surfaces has both practical and academic interests.
