アロフェンのSi/Al比と表面酸性強度との関係に関する分子軌道論的考察
Allophane has a morphology of aggregates composed of fine hollow spherules with the diameter of 3.5-5.0nm. The compositions of the wall of hollow spherules are in a range about 0.5 to 1.0 in terms of Si/Al atomic ratio. The measured surface acidity was higher in strength for allophane with higher Si/Al atomic ratio than for that with lower ratio. It was difficult for allophane to know detailed mechanism of its surface acid phenomenon by means of only experimental methods.
