Perovskite Type

Catalytic combustion technology can effectively reduce the temperature of the combustion reaction and significantly inhibit the formation of NOx. Perovskites catalyst materials have high stability, varied chemical composition, and low cost etc. A combination of catalytic combustion technology and perovskite catalyst materials has great significance for energy industry and environment protection. However, improving lower temperature catalytic activity and high temperature thermostability performance of perovskite catalyst is still major problem. Some researchers have improved the activity and stability of perovskite catalysts for methane combustion by different preparation methods. The structure and preparation methods of perovskite-type oxide catalysts are presented.

The LaBO3/HZSM-5 samples were prepared by the impregnation method. The structure of catalysts was examined by XRD. The catalytic activity for the combustion of soot particulate was evaluated by a technique of the temperature-programmed reaction. In the LaBO3/HZSM-5 catalyst, the Mn as B-site ion, the catalyst was the good candidate catalyst for the soot catalytic combustion. In the LaMnO3/HZSM-5 catalyst, the catalytic activity was tunable by changing the metal components of the perovskite-type oxide at B-site, the Fe partial substitution for Mn of LaMnO3/HZSM-5 enhanced the catalytic activity, and the combustion temperature of soot particle was lower than LaMnO3/HZSM-5 sample without substitution, corresponding Tm of 401oC and the selectivity of CO2 77.0%.
