TL;DR: Here it is shown that by doing so, the complexity limit can be extended much further and the power of the FOCUS algorithm has been demonstrated with the solution of the structure of the zeolite TNU-9, the most complex zeolites known to date.

TL;DR: In this article, the selective catalytic reduction of NOx with ammonia (NH3-SCR) has been studied over Cu-CHA catalysts in which the loading of copper species was achieved using three different synthetic routes: two are based on post-synthetic treatment of the zeolite material (via aqueous or vapor phase) and a third involves the direct synthesis of a Cu-loaded SAPO-34.

TL;DR: The first large pore (free diameter > 7 A) metal phosphonates have been prepared as divalent metal N,N'-piperazinebis(methylenephosphonate)s that possess pores greater than ca.

TL;DR: A combination of molecular modeling and Rietveld refinement using synchrotron powder diffraction data confirms the proposed topology of as-made TNU-9 and suggests three or possibly four different sites for the organic within the complex pore structure.

TL;DR: A 'co-templating' strategy supported by molecular modelling has been used to prepare, for the first time, silicoaluminophosphates with the SAV and KFI framework topologies, each of which has a three-dimensionally connected pore system with high specific volume.
