通过对吸附二甲吡啶的程序升温解吸，阐明了在氧化铝载体上沉积二氧化硅制备的二氧化硅-氧化铝的酸型、酸强度和酸量的特征变化。随着二氧化硅沉积的增加，氧化铝的Lewis酸位点转变为Bronsted酸位点，酸强度也发生变化。
A temperature-programmed desorption of adsorbed dimethylpyridine clarified the characteristic changes in acid type, acid strength, and acid amount of silica–alumina prepared by depositing silica on an alumina support. Lewis acid sites of the alumina changed into Bronsted acid sites together with a change in the acid strength with increasing silica deposition.
