G. Groppi et al., PREPARATION AND CHARACTERIZATION OF HEXAALUMINATE-BASED MATERIALS FORCATALYTIC COMBUSTION, Applied catalysis. A, General, 104(2), 1993, pp. 101-108
A simple preparation method for barium hexaaluminate-based catalysts t
o be used in catalytic combustion is described. Morphological and phys
ico-chemical characterization data are given for Ba-Al-O (with Ba/Al=1
/12) and for Ba-Mn-Al-O (with Ba/Mn/Al= 1/0.5/11.5; 1/1/11; 1/2/10) sa
mples calcined at different temperatures. The preparation method here
proposed provides stable materials with a surface area of 15 m(2)/g af
ter calcination at 1400 degrees C. The structural and morphological pr
operties, ae well as the results of activity tests in methane combusti
on, compare well with those reported in the literature for samples wit
h the same composition and prepared according to a more complex prepar
ation route.
