Lines of Research of Nano Hybrid Lab Group
Current interests of NHL Group involve the development of novel efficient recyclable and sustainable catalysts (metal nanoparticles, organometallic- and organo-catalysts), the development of new functional hybrid silica-, poly ionic liquid-, polydopamine-based materials as well as carbon nanoforms-based materials (fullerenes, nanotubes, nanohorns, nanodiamonds and graphene) and the development of novel protocols for the chemical functionalization of nanocarbons.
Ionic Liquid-like hybrid materials, based mainly on imidazolium or thiazolium, can be prepared both from molecular structures such as fullerene or POSS, or incorporated into 3D materials such as amorphous and mesostructured silica, or even into carbon nanoforms. The resulting hybrids may have a monolayer or a cross-linked network of IL-moieties and can be employed as scavengers, as catalysts, as support for metal nanoparticles or even as precursors for polyamine-based catalysts.
Carbon nanoforms can be successfully employed as platforms for the immobilization of catalytic moeities. They can act as "simple" but highly structured supports with well defined shapes and sizes or they can actively participate during the catalytic cycle.
POSS are used as cubic inorganic core in the preparation of hybrid homogeneous or heterogeneous catalysts. Ionic-Liquid/POSS hybrids exhibit a synergic proximity effect which enhances the catalytic activity of IL in the fixation of CO2 into cyclic carbonates. These hybrid systems can also be covalently immobilized on the surface of different metal oxides or can be employed for stabilizing Pd(II) and Pd(0) species in C-C bond forming coupling processes.
The aim of the present project is to discover novel synthetic procedures for the covalent functionalization of nanocarbons in order to widening chemists' tools for "playing" with them. Whenever possible, this new tools will be employed for practical applications of the modified nanocarbons.
The aim of the present project is to develop novel molecular and polymeric systems in order to improve organic photovoltaic devices performances even through the optimization of synthetic procedures.
