[EN] Unlike homogeneous catalysts that are often designed for particular reactions, zeolites are heterogeneous catalysts that are explored and optimized in a heuristic fashion. We present a methodol. for synthesizing ...

[EN] No ligands needed: Rhodium complexes supported on HY zeolite catalyze the formation of C[BOND]C bonds by a new mechanism involving cooperation between the metal species and Brønsted acid sites of the zeolite support ...

[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 ...

[ES] El agua es un recurso esencial para la sociedad y es necesario garantizar el suministro de agua de calidad. Esto no es sencillo, ya que sólo entre el 0,6% y el 0,9% del agua del planeta es fácilmente accesible como ...

[EN] The bimetallic nanocluster catalyst structure can change during pretreatment and reaction, thus in situ characterization techniques are required for a proper analysis of the active sites. In situ XAFS and DRIFTS were ...

[EN] C1 chemistry, which is the catalytic transformation of C1 molecules including CO, CO2, CH4, CH3OH, and HCOOH, plays an important role in providing energy and chemical supplies while meeting environmental requirements. ...

[EN] Since the early reports by Barrer in the 1940s on converting natural minerals into synthetic zeolites, the use of precrystallized zeolites as crucial inorganic directing agents to synthesize other crystalline zeolites ...

[ES] Los carbenos representan una clase de reactivos altamente potentes utilizados en el campo de la síntesis orgánica, que muestran la capacidad de participar eficazmente durante los procesos de inserción en una amplia ...

En el presente trabajo se ha estudiado la actividad catalítica de diferentes tamices moleculares sólidos con acidez de Lewis, sintetizados en el Instituto de Tecnología Química, utilizándolos como catalizadores en reacciones ...

[EN] This paper reports the activity of different Ce-BEA zeolites for the catalytic oxidation of trichloroethylene and it is focused on determining the nature of the catalyst active sites. The study was made by using a ...
