Crystal engineering of zeolites with graphene.
Achieving control over the morphology of zeolite crystals at the nanoscale is crucial for enhancing their performance in diverse applications including catalysis, sensors and separation. The complexity and sensitivity of zeolite synthesis processes, however, often make such control both highly empirical and difficult to implement. We demonstrate that graphene can significantly alter the morphol...
متن کاملAb initio structure determination of interlayer expanded zeolites by single crystal rotation electron diffraction.
Layered solids often form thin plate-like crystals that are too small to be studied by single-crystal X-ray diffraction. Although powder X-ray diffraction (PXRD) is the conventional method for studying such solids, it has limitations because of peak broadening and peak overlapping. We have recently developed a software-based rotation electron diffraction (RED) method for automated collection an...

متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
متن کاملCrystal Structure of Nonaaquayttrium(III) Bromate at 100 K
The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...
