Abstract:
In this work, we perform an in-depth experimental and computational study about the structure-directing effect of two new chiral organic quaternary ammonium dications bearing twoN-methyl-prolinol units linked by a xylene spacer inparaormetarelative orientation, displaying [read more]

Structural characterization of HPM-7, a more ordered than expected germanosilicate zeolite

Authors: Lu, P; Zhang, YP; Mayoral, A; Gomez-Hortiguela, L; Camblor, MA

Article.
Dalton Trans.. vol: 49. page: 1477-9226.
Date: jun-07. 2020.
Doi: 10.1039/d0dt00818d.

Abstract:
HPM-7, a germanosilicate synthesized using long imidazolium-based dications with two different linkers, is shown to possess the POS topology, although disorder may exist but it is very difficult to discern. First, three simple ordered polymorphs (POS-A to POS-C) [read more]

Synthesis of a germanosilicate zeolite HPM-12 using a short imidazolium-based dication: structure-direction by charge-to-charge distance matching

Authors: Lu, P; Gomez-Hortiguela, L; Gao, ZH; Camblor, MA

Article.
Dalton Trans.. vol: 48. page: 1477-9226.
Date: DEC 28. 2019.
Doi: 10.1039/c9dt04089g.

Abstract:
A short imidazolium based dication, with only three methylene units in the spacer linker, selectively directs the crystallization of zeolite HPM-12 (*UOE) as long as there is enough germanium present in the synthesis gel. The integrity of the dication [read more]

Viologen-modified electrodes for protection of hydrogenases from high potential inactivation while performing H-2 oxidation at low overpotential

Authors: Oughli, AA; Velez, M; Birrell, JA; Schuhmann, W; Lubitz, W; Plumere, N; Rudiger, O

Dalton Trans.. vol: 47. page: 1477-9226.
Date: AUG 21. 2018.
Doi: 10.1039/c8dt00955d.

Abstract:
In this work we present a viologen-modified electrode providing protection for hydrogenases against high potential inactivation. Hydrogenases, including O-2-tolerant classes, suffer from reversible inactivation upon applying high potentials, which limits their use in [read more]

Synthesis of pure silica MFI zeolites using imidazolium-based long dications. A comparative study of structure-directing effects derived from a further spacer length increase

Authors: Lu, P; Gomez-Hortiguela, L; Camblor, MA

Article.
Dalton Trans.. vol: 47. page: 1477-9226.
Date: jun-14. 2018.
Doi: 10.1039/c8dt01127c.

Abstract:
Length-dependent structure direction of linear methylimidazolium-based dications towards MFI zeolite, previously known only for the tetramethylene spacer, has also been found for octamethylene and decamethylene spacers. This works only under highly concentrated conditions, whereas dilution always tends to favor TON, a default [read more]

Abstract:
In the present study a porous lamellar zirconium phosphate heterostructure (PPH) formed from zirconium(IV) phosphate expanded with silica galleries (P/Zr molar ratio equal to 2 and (Si + Zr)/P equal to 3) was prepared to host noble metals. [read more]
