Аннотация

In this study, a series of cerium dioxide catalysts with varying hydrothermal temperatures and times were synthesized using the hydrothermal method, without the use of templates. The impact of varying hydrothermal conditions on the activity of cerium dioxide catalysts was investigated through experiments to examine their oxidation characteristics in soot combustion. Among the conditions tested, the hydrothermal conditions of 140 °C and 6 h yielded the most optimal catalytic oxidation of soot, with a combustion characteristic temperature (Tp) of 552 °C and a reduction of 122.9 °C. The integrated combustion index (S) and combustion stability coefficient (Rw) were found to be 27.97 × 108 %2min−2°C−3 and 90.76 × 105, respectively. The indices of S and Rw exhibited an improvement of 51.1% and 36.93%, respectively.
