Non-conventional methods and media for the activation and manipulation of carbon nanoforms

2013

Very often, chemical transformations require tedious and long procedures, which, sometimes, can be avoided using alternative methods and media. New protocols, enabling us to save time and solvents, allow us also to explore new reaction profiles. This Tutorial Review focuses on the physical and chemical behavior of carbon nanoforms, CNFs (fullerenes, nanotubes, nanohorns, graphene, etc.) when non-conventional methods and techniques, such as microwave irradiation, mechano-chemistry or highly ionizing radiations are employed. In addition, the reactivity of CNFs in non-conventional media such as water, fluorinated solvents, supercritical fluids, or ionic liquids is also discussed.

POSS-based 3D functional networks as catalysts for the conversion of carbon dioxide

2023

Oggi lo sviluppo di processi sostenibili è al centro dell'attenzione a causa delle emergenze climatiche. La Chimica Verde, con i suoi dodici principi sviluppati da Paul Anastas, si concentra sullo sviluppo di processi alternativi e più rispettosi dell'ambiente. Questa branca della chimica mostra come concetti quali la prevenzione dei rifiuti, l'uso di materie prime rinnovabili e la catalisi siano di grande importanza per rendere un processo più sostenibile. In questo contesto, l'anidride carbonica (CO2) rappresenta una delle materie prime più abbondanti, non tossiche e rinnovabili. La possibilità di riutilizzare la CO2 e di trasformare questa molecola in prodotti a valore aggiunto come i ca…

Covalently Supported Imidazolium Salts In Catalysis

2020

Synthesis and catalytic applications of supported imidazolium salts covalently linked to the proper support are described. As supports here we report, among others, the use of amorphous and mesoporous silica, polyhedral oligomeric silsesquioxanes, magnetic-based silica, polystyrenes, halloysite nanotubes, carbon nanoforms such as fullerenes, carbon nanotubes, carbon nanohorns, graphene. The catalytic applications have been divided into two main sections, metal-free based and metal-based reactions.
