High Temperature Catalytic Combustion over Cation-substituted Barium Hexaaluminates

Abstract
The combustion activities of various oxide catalysts were investigated using BaO·6Al2O3 as support. Conventional impregnation of oxide catalysts only lead to a decrease in surface area of the support. Cation-substituted barium hexaaluminates generally retained the large surface area. In particular, BaMnAl11O19−α′, showed the excellent activity and the large surface area of 13.7 m2/g after calcination at 1300 °C.
