The enhancement of low-temperature combustion of diesel PM through concerted application of FBC and perovskite

In this study, we attempted to improve diesel particulate matter (PM) combustion by the simultaneous application of a fuel-born catalyst and a perovskite catalyst. The experiment was simulated by mixing fuel-borne catalyst (FBC)-incorporated PM with perovskite catalyst in a physical manner. FBC-incorporated PM was achieved satisfactorily using a self-constructed PM generator. Through temperature-programmed oxidation (TPO), the catalyst combination of Fe/Ce FBC and La0.7K0.3FeO3 effectively improved the low-temperature combustion of diesel PM, with superior performance to that of the Fe/Ce FBC–Pt/Al2O3 combination.
