Abstract
Effect of additives on the surface area of oxide supports was investigated to use them for combustion catalysts above 1000 °C. An addition of BaO to Al2O3 was found to suppress the decrease of its surface area at elevated temperatures. The maximum surface area, 6.0 m2/g, was obtained for (BaO)0.14(Al2O3)0.86 after calcination at 1450 °C. The effect of BaO on the surface area of alumina is attributed to the formation of BaO·6Al2O3.Keywords
