摘要
目前,新型微孔无机固体化合物的合成是一个活跃的研究领域,本文报道在R-Ga2O3-P2O5-H2O体系中(R=有机模板剂)系列磷酸镓分子筛的合成与结构的研究,合成的十二种磷酸镓分子筛(命名为GaPO4-Cn,n=1-12)中,GaPO-4-C4,-C5和-C12分别与AlPO-4一21、AlPO4-14和AlPO4-25具有相似的骨架结构,其它为新的磷酸镓分子筛晶相。
A novel family of gallophosphate molecular sieves (namely GaPO_(4)-Cn,n= 1-12) was synthesized in R-Ga_(2)O_(3)-P_(2)O_(5)-H_(2)O systems (R=organic templating agents.) and characterized by means of XRD, IR, chemical composition analysis, gas adsorption and MAS NMR techniques. The crystal structures of GaPO_(4)-C3 and GaPO_(4)-C4 were determined by Single Crystal X-ray Diffraction. The various gallophosphate molecular sieves have intracrystalline adsorption pore sizes from 3 to 6 A.
