A Novel Hexaaluminate Material: Preparation, Characterization and Catalytic Activity in Methane Combustion

Abstract:

A novel hexaaluminate material Ca_0.6La_0.4Fe_xMn_1-xAl₁₁O₁₉ was prepared by a micro-emulsion method, and then washcoated on the cordierite substrates to produce monolithic catalysts. The obtained hexaaluminates were characterized by X-ray diffraction and scanning electron microscope. Results show that the particles of the prepared hexaaluminates samples are well-proportioned and small, and that the lower-quantity replacement of Mn²⁺ with Fe³⁺ is of benefit to forming single hexaaluminates crystal phases. After the partial replacement of Mn²⁺ with Fe³⁺ in hexaaluminate, the catalytic activity in methane combustion improved.
