开放骨架磷酸铝合成中F-对有机胺结构导向效应的影响
Influence of F-on the Structure-directing Effect of Organic Amines in the Synthesis of Open-framework Aluminophosphates
摘要
Abstract
The significant influence of F- on the structure-directing effect of ethylenediamine( en) and dieth-ylenetriamine( deta) in the synthesis of open-framework aluminophosphates was investigated. For the system with ethylenediamine, in the absence of F-, layered aluminophosphate Al2P2O9·NH3(CH2)2NH3(UiO-13) was obtained from the initial mixture with n( Al2 O3 ):n( P2 O5 ):n( en):n( H2 O)=1. 0:1. 5:18. 0:147 un-der hydrothermal condition, while layered aluminophosphate AlF(HPO4)·NH2(CH2)2NH2(1) was obtained from the initial mixture with n(Al2O3):n(P2O5):n(en):n(HF):n(H2O)=1. 0:1. 5:18. 0:3. 0:147. The results suggested that the F-significantly affected the structure-directing effect of ethylenediamine. For the system with diethylenetriamine, a three-dimensional ( 3D ) open-framework aluminophosphate Al4P5O20(H2O)2·C4N3H16(AlPO-CJ31) was synthesized from the initial mixture with n(Al2O3):n(P2O5):n(deta):n(H2O)=1. 0:4. 0:3. 0:153 under hydrothermal condition, while a one-dimensional(1D) alu-minophosphate Al2P4O10(OH)3F·C4N3H15(2) was crystallized from the similar initial mixture in the presence of F-[n(Al2O3):n(P2O5):n(deta):n(HF):n(H2O)=1. 0:4. 0:3. 0:3. 0:153]. The results indicated that the structure-directing effect of diethylenetriamine was significantly altered by F-. The structural proper-ties of open-framework aluminophosphates UiO-13 , 1 , AlPO-CJ31 and 2 were analyzed in detail and the influ-ence of F- on the structure-directing effect of ethylenediamine and diethylenetriamine was discussed.关键词
