Abstract

An efficient Pd-decorated La_0.8Sr_0.2Co_0.2Fe_0.8O_3-δ (LSCFO) catalyst for the catalytic deoxidation of landfill gas (LFG) at low temperature has been developed. Synergism between the Pd coating and the LSCFO substrate in inducing the catalytic deoxygen reaction (CDR) was observed. The results demonstrated that the Pd-decorated LSCFO catalysts studied showed excellent deoxygen performances and a low light-off temperature of about 225 °C, which is lower than the typical temperatures used in conventional catalytic deoxygen processes (T > 300 °C). A probable cause of this synergism may be the cooperative action when the Pd catalyst was coated on an active deoxygen substrate.
