Abstract

In the present study, redox ( CeO2, SnO2, Pr6O11 and Mn3O4) and non-redox ( Gd2O3, La2O3 ZrO2 and HfO2) metal oxides were successfully synthesised using the EDTA–citrate complexing method and tested for soot oxidation activity. The characterization of the metal oxides is carried out using FTIR, XRD, BET surface area, pore volume analyser, SEM and TEM. The redox nature and metal–oxygen bond information of the metal oxides are obtained from XPS analysis. In redox metal oxides, three critical parameters [lattice oxygen binding energy, reduction temperature and Δr (ionic size difference of the co responding metal oxide oxidation states)] govern the soot oxidation activity. Among the redox metal oxide samples,
