new abc 6 Net molecular sieves znapo 57 and znapo 59 framework charge density induced transition from two to three dimensional porosity
Microporous and Mesoporous Materials, 2014Co-Authors: Robert W Broach, N Greenlay, Paulina Jakubczak, Lisa M Knight, Stuart R Miller, John P S Mowat, Justin E Stanczyk, Gregory J LewisAbstract:Abstract In a quest to make AlPO-based compositions with higher framework charge densities, the investigation of the chemistry of the diethyldimethylammonium (DEDMA) and ethyltrimethylammonium (ETMA) Structure directing agents (SDA) has yielded two new ABC-6 Net framework topologies. DEDMA leads to MeAPO-57, which is the first example of an ABC-6 Net Structure with a 5-layer repeat sequence. The Structure was solved for the ZnAPO version in the space group P-3c and refined with the lattice parameters a = 13.3538 and c = 25.5664 A, which included a doubled c -axis to account for the alternating Al/Zn and P occupancy of the T-atom sites. The identical synthesis, except for the substitution of DEDMA with ETMA, leads to MeAPO-59, which is the first example of an ABC-6 Net Structure with a 7-layer repeat sequence. This Structure was also solved for the ZnAPO version in the space group P-3c and refined on the lattice parameters a = 13.3756 and c = 36.2118 A, which also included a doubled c -axis. Product framework charge densities could be altered by adding Si or changing the SDA/H 3 PO 4 levels. At high SDA/H 3 PO 4 levels, the addition of Si to syntheses that yield MeAPO-57 or MeAPO-59 leads to MeAPSO-64, which has the BPH topology. Lowering the SDA/H 3 PO 4 in both ETMA and DEDMA systems leads to MeAPO-67 with the LEV topology, another ABC-6 Net Structure with a 9-layer repeat sequence. The ZnAPO-57, ZnAPO-59, LEV and BPH topologies all exhibit two-dimensional 8-ring pore systems perpendicular to the c -axis. Access to diffusion along the c -axis increases with SDA/H 3 PO 4 levels and framework charge density in the order LEV c -axis.
