[EN] It has been possible to efficiently synthesize high-silica ERI and AFX zeolites with nano-sized primary crystallites (30-200 nm). This was achieved by using a dicationic and rigid organic structure directing agent ...
[EN] The direct preparation of different iron-containing Beta and CHA zeolites has been attempted under diverse synthesis conditions, including in alkaline and fluoride media, to evaluate the influence of their physicochemical ...
[EN] The preparation of novel efficient catalyststhat could be applicable in industrially important chemical processeshas attracted great interest. Small subnanometer metal clusters can exhibit outstanding catalytic ...
[EN] The preparation of the iron-containing SSZ-39 zeolite is described for the first time through two different synthesis methods: post-synthetic cation exchange and one-pot synthesis. The nature and stability of the iron ...
[EN] From theoretical calculations and a rational synthesis methodology, it has been possible to prepare nanocrystalline (60-80 nm) chabazite with an optimized framework Al distribution that has a positive impact on its ...
Martín García, Nuria(Universitat Politècnica de València, 2018-01-15)
La presente tesis doctoral se centra en la preparación de zeolitas de poro pequeño (3.5-4 Å), en concreto, aquellas cuya estructura presenta además cavidades grandes. Este tipo de materiales ha despertado un enorme interés ...
