[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] A series of organic-inorganic hybrid bifunctional organosiliceous catalysts with accessible pendant amine groups as single basic sites (such as propylamine, diethylamine, pyrrolidine) and Pd nanoparticles was prepared ...

[EN] Organic inorganic hybrid materials with different levels of structuration and porous hierarchy and one or several types of active sites in the framework can catalyze multistep chemical processes in a one-pot reactor ...

[EN] The catalytic performance of Fe-catalysts in selective catalytic reduction of nitrogen oxides with ammonia (NH3-SCR) strongly depends on the nature of iron sites. Therefore, we aimed to prepare and investigate the ...

[EN] The application of layered zeolites of MWW topology in environmental catalysis has attracted growing attention in recent years; however, only a few studies have explored their performance in selective catalytic reduction ...

Zeolites with MWW topology (MCM-22, ITQ-2, and MCM-36) exchanged with copper and iron were studied as catalysts for selective catalytic reduction of NO with ammonia. It was shown that delamination and pillaring of layered ...

[EN] Understanding the interactions that govern the photophysical behaviour of Metal-organic frameworks (MOFs) and their composites is paramount for their photochemical and photonic applications. In this work, we report ...

[ES] La química verde, cuyos procesos fueron definidos por Paul Anastas y John Warner, intenta definir procesos químico más amigables con el medio ambiente mediante el cumplimiento de ciertos principios, entre los que se ...

The ability to produce catalytic nanoparticles with controlled properties is key to developing and producing heterogeneous catalysts with optimized activity and selectivity. No less important is to maximize the nanoparticle ...

[EN] Different metalorganic lamellar hybrid materials based on associated nanoribbons were synthesized by the use of alkyl-benzyl monocarboxylate spacers, containing alkyl tails with variable lengths, which acted like ...
