0·5 CH3OH, crystallize in the triclinic space group with unit cell dimensionsa=14·278(4),b=16·932(4),c=9·057(4) Å, α=97·40(3), β=92·07(3), γ=85·32(2)° andZ=4. The structure was refined by a block-matrix least-squares procedure to finalR 0·050 andR w 0...
Hierarchical zeolites, consisting of dual meso-/micropores, have shown remarkable catalytic performance for reactions involving bulky molecules in the past decades [28]. Among the hierarchical zeolites, two-dimensional (2D) zeolite nanosheet and its assembly structures are unique. The assembly increases...
