Abstract

An efficient Pd-coated La_0.1Sr_0.9Co_0.2Fe_0.8O_3-δ (LSCF-1928) catalyst for total oxidation of methane under landfill gas at low tmeperature has been developed. Synergism was observed between Pd coating and LSCF-1928 substrate. When Pd coating on LSCF-1928, we used electroless plating method and conformed characteristic of catalyst through TPR(Temperature Programmed Reduction) analysis, XRD(X-ray Diffraction) analysis, SEM(Scanning Electron Microscope). The results demonstrated that the Pd coated LSCF-1928 catalysts showed higher performance than non-Pd LSCF-1928. Pd coated LSCF-1928 had low total oxidation temperature of methane (< 475 °C) which is lower than total oxidation temperature of methane about non-Pd LSCF-1928 catalysts (= 475 °C). Also, O2 conversion rate was higher than non-Pd LSCF-1928 at same temperature.
