Abstract

<p>Catalytic combustion of soot was performed over ZnO:CeO₂ catalysts obtained via a non‑alkoxide sol-gel route. Different kinetics parameters were calculated through thermal analyses, thus, enabling the correlation between the experimental data and the decomposition mechanisms probably associated with the soot decomposition in each case.</p> (AU)
