The paired Al species pre-formed in Al-rich amorphous aluminosilicates were transcribed into high-silica CHA-type zeolite frameworks under hydrothermal conditions, which offers a new approach to creating paired Al sites in zeolite frameworks. This Al-pair-rich CHA exhibited a higher Sr uptake than the control CHA zeolite synthesized by the conventional procedure.
在富铝无定形硅铝酸盐中预先形成的成对铝物种在水热条件下被转变成高硅CHA型沸石骨架，这为在沸石骨架中创建成对铝位点提供了一种新方法。这种富含铝对的CHA对锶的吸收能力高于通过传统方法合成的对照CHA沸石。
