The hydrothermal approach was used to develop a sequence of copper-doped KOMS2, which was applied for soot oxidation. XRD pattern showed the tetragonal phase of KOMS2 and copper-doped KOMS2.SEM analysis showed all samples showed rod-like structures. Soot TPR results revealed the copper doped KOMS2 had bulk oxygen radicals along with surface adsorbed and lattice oxygen radicals. Compared to copper-doped KOMS2 samples, KOMS2 possessed the most surface-adsorbed oxygen radicals. Using the TGA instrument, the performance of KOMS2 and copper-doped samples for soot oxidation activity was studied. KOMS2 exhibited the best soot oxidation activity with T50% of 395 °C.
