[EN] The nature of organic structure directing agents (OSDAs) is of paramount importance in the final properties of zeolites, particularly the framework and porosity. Recently, the use of P-containing OSDAs has been employed ...

The medium pore zeolite, TNU-9, is prepared and studied for the selective catalytic reduction (SCR) of NO using C3H8 as the reducing agent. The catalytic activity of TNU-9 zeolites for the SCR is comparable to other known ...

[EN] A new photochemically induced [2+2] cycloaddition route for the synthesis of amines has been successfully applied for the preparation of a series of organic structure directing agents (OSDA's) that has been found to ...

[EN] Two different heterogeneous catalysts carrying aryl-sulfonic moieties, in which the aromatic ring was either fluorinated or not, were successfully synthesized. The multi-step synthetic approaches implemented involved ...

[EN] The activation of precursor-dependent Pd nanoparticles was comprehensively followed by in situ X-ray absorption spectroscopy on two inorganic supports for rationalizing the final catalytic activity. Two series of ...

This study reports the experimental characterization of the hydrostatic properties of arsenolite (As4O6), a molecular solid which is one of the softest minerals in the absence of hydrogen bonding. The high compressibility ...

La reducción de óxidos de nitrógeno sobre materiales zeolíticos intercambiados con metales de transición es una de las rutas más prometedoras para la disminución de estos contaminantes en emisores móviles. Sin embargo, existe ...

Adsorption of CO2 and CH4 has been measured on the Na-, K-, and Cs-forms of zeolite Rho (0 9 bar; 283 333 K). Although CH4 is excluded, CO2 is readily taken up, although the uptake at low pressures decreases strongly, in ...

[EN] The charge matching effect has been found to be an important parameter driving the synthesis towards particular zeolite frameworks. This has been evidenced by isomorphous incorporation of Aluminium into the zeolite ...
