In this PhD thesis, different types of hybrid organic-inorganic materials were studied as solid sorbents for the carbon dioxide capture, in order to give additional hints to the comprehension of phenomena playing an important role in CO2 adsorption processes. In the first part, hybrid organic-inorganic SBA-15 silicas functionalized with variable amount of amino groups were studied aiming to evaluate the influence of the different basic species on CO2 capture ability. Afterwards, it was decided to study the influence of siliceous support properties on the adsorption process. For this purpose, s

The separation of industrially important gases into pure supplies that can be used for many practical applications is based mainly on energy intensive methods such as the cryogenic distillation which is costly and energy intensive.

In the first part of the thesis it is presented a brief review of supramolecular chemistry concepts, chemistry of boron and also the main methods for boron removal (first chapter) and, also, the objectives of this thesis (second chapter). The third chapter ex

Abstract:
Doutoramento em Física<br>Luminescent solar concentrators are inexpensive devices that aim to increase the efficiency of photovoltaic cells and promote the urban integration of photovoltaic devices, with unprecedented possibilities of energy harvesting through the façade of buildings, urban furniture or wearable fabrics. Generally, they consist of a transparent matrix coated or doped with active optical centres that absorb the incident solar radiation, which is re-emitted at a specific wavelength and transferred by total internal reflection to the edges where the photovoltaic cells are located

Abstract:
The acid and base catalyzed simultaneous twin polymerization (STP) of various 2,2′-disubstituted 4H-1,3,2-benzodioxasiline derivatives 2a–d with 2,2′-spirobi[4H-1,3,2-benzodioxasiline] (1) are presented in this paper. The products are nanostructured ternary organic–inorganic hybrid materials consisting of a cross-linked organic polymer, silica and a disubstituted polysiloxane. It can be demonstrated whether and in which extent the copolymerization of the two inorganic fragments of 1 and 2 takes place among the STP and how the molar ratio of the two components determines the structure formation

Ce mémoire rapporte la préparation et l'étude de matériaux hybrides organiques-inorganiques à base de titane où les deux réseaux sont liés par des liaisons titane-carbone stables. Différents précurseurs dans lesquels deux groupes cyclopentadienyltitane sont reliés par des espaceurs variés ont été préparés. Ces espaceurs comprennent des groupes aromatiques et hétéroaromatiques linéaires ainsi que des groupes aromatiques disubstitués par des chaînes alkyle. Ces complexes dimétalliques, où le titane est aussi lié à trois groupes labiles, ont été ensuite hydrolysés dans les conditions du procédé s

During this work, we have synthesised and completely characterised four new ligands, twenty two novel coordination complexes and thirteen new hybrid Metal- Organic Framework (supramolecular and coordination polymers) silver(I), Zinc(II) and copper(II)-containing with fascinating and intriguing structural architectures. To achieve these results under mild conditions, we have chosen three secondary building units or building blocks (SBU): cationic unit by the trinuclear copper [Cu3(μ3-OH)(μ- C3H3N2)3]2+, neutral complexes such as [M2(O2CC10H6CO2)].nH2O and [M3(C9H3O6)2]n.nH2O (where M = Cu(II)

Abstract:
During the PhD, most of the efforts have been spent to study and to optimize the performance of third generation solar cells, such as dye sensitized solar cells (DSSCs) and hybrid organic/inorganic Perovskite solar cells (PSCs). In particular, the attention has been focused on optimization of the fabrication process and on the implementation of carbon based materials to optimize different aspects of the cell. An original technique, the Vacuum-vapor assisted solution processing (V-VASP) was designed and developed to deposit glassy perovskite films without an inert atmosphere, therefore with lo

>Magister Scientiae - MSc<br>Due to the rapid depletion of fossil fuel reserves and the production of environmentally harmful by-products such as carbon dioxide, there is an urgent need for alternate sustainable clean energy. One of the leading candidates in this endeavour is hydrogen, which can be used as an energy carrier since it has a high energy density, zero emissions and is produced from non-depletable resources such as water. The major challenge hindering a hydrogen economy is the lack of safe and effective storage technologies for mobile applications. A prospective solution to this pr
