Abstract

The catalytic combustion of particulate matter (PM) is one of the key technologies to meet emission standards of diesel engine system. Therefore, we herein suggest Ag loaded La_0.6Sr_0.4Co_0.2Fe_0.8O₃ perovskite web catalyst. They were produced by the electrospinning method. FE-SEM, EDS mapping, XRD, XPS were studied to investigate the crystal and morphological structures of loaded Ag particles and La_0.6Sr_0.4Co_0.2Fe_0.8O₃ perovskite web catalyst. Following the catalytic soot oxidation, we found that the Ag loaded La_0.6Sr_0.4Co_0.2Fe_0.8O₃ perovskite web catalyst showed the higher catalytic activities (e.g., T₅₀ = 490 ^oC) than the only La_0.6Sr_0.4Co_0.2Fe_0.8O₃ perovskite web catalyst (e.g., T₅₀ = 586 ^oC). Thus, this finding suggests that Ag loaded La_0.6Sr_0.4Co_0.2Fe_0.8O₃ perovskite web catalyst can be a promising candidate for enhancing the soot oxidation.
