Paired Ga sites represented by the Ga-O-Si-O-Ga sequence were firstly formed intentionally in CHA-type zeolite frameworks the transcription of pre-formed paired Ga species in a Ga-rich amorphous silica-gallia under seed-assisted hydrothermal conditions. Such paired Ga sites behaved as ion-exchange sites for capturing divalent cation, Co.
由Ga-O-Si-O-Ga序列表示的成对Ga位点首先在CHA型沸石骨架中通过在种子辅助水热条件下在富Ga无定形硅铝酸盐中预先形成的成对Ga物种的转录而有意形成。这种成对的Ga位点作为捕获二价阳离子Co的离子交换位点。
