Full textL'obiettivo di questa tesi è l'applicazione della spettroscopia di fotoemissione allo studio di nanoparticelle supportate e di sistemi a bassa dimensionalità. Ad una primo periodo dedicato allo sviluppo del rivelatore e del software per un nuovo analizzatore d'energia per elettroni installato presso la linea di luce SuperESCA ad Elettra, è seguita una fase durante la quale ho eseguito una serie di esperimenti mirati ad esplorare le potenzialità del nuovo apparato sperimentale. Il primo risultato ottenuto riguarda la comprensione della relazione che intercorre tra le variazioni della reattività chimica del sistema Pd/Ru(0001) e il numero degli strati di Pd cresciuti in modo pseudomorfico sul substrato di rutenio. La risoluzione temporale raggiunta con la nuova strumentazione ci ha permesso di studiare processi dinamici su una scala temporale fino ad ora inaccessibile per la spettroscopia di fotoemissione dai livelli di core: in particolare abbiamo studiato la crescita del grafene ad alta temperatura sulla superficie (111) dell'iridio e la reattività chimica di nanocluster di Pt supportati su MgO. Nel primo caso abbiamo messo in evidenza come la formazione del grafene proceda attraverso la nucleazione di nano-isole di carbonio che assumono una peculiare forma di cupola. Nel secondo caso siamo riusciti a seguire sia la dinamica del processo di adsorbimento di CO, sia la reazione CO + 1/2 O2 -> CO2 sulle nanoparticelle di Pt depositate su un film ultra-sottile di ossido di magnesio. Infine, abbiamo caratterizzato la morfologia di nanoparticelle di Pd, Pt, Rh e Au cresciute su diversi substrati a base di carbonio, in particolare grafite, nanotubi a parete singola e grafene. Tra i vari risultati abbiamo compreso come l'interazione metallo-substrato dipenda dalla dimensione delle nano-particelle e abbiamo evidenziato il ruolo centrale dei difetti del substrato nei processi di nucleazione e intercalazione.
The objective of this thesis is the application of photoelectron spectroscopy for the investigation of supported nanoclusters and low-dimensional systems. After a first stage devoted to the development of the detector and the software for the electron energy analyser installed on the SuperESCA beamline at Elettra, during the PhD project I've performed a series of experiments aimed to explore the capabilities of the new experimental apparatus. One of the first results concerns the understanding of the relation between the modifications in the chemical reactivity of the Pd/Ru(0001) system and the thickness of the pseudomorphically grown Pd overlayer. The temporal resolution achieved with the new experimental set-up allowed us to study dynamical processes on a new time scale, in particular the graphene growth process at high temperature on the Ir(111) surface and the chemical reactivity of Pt nanoclusters supported on MgO. In the former case, we discovered that graphene formation proceeds via preliminary nucleation of dome-shaped C nano-islands. In the second case, we succeded in following both the dynamics of CO adsorption process and the CO + 1/2 O2 -> CO2 reaction on Pt nanoclusters grown on a ultra-thin film of magnesium oxide. Finally, the morphology of Pd, Pt, Rh and Au nanoclusers grown on different carbon-based substrates (namely graphite, single-walled carbon nanotubes and graphene) has been characterized. Among the results we report the understanding of the dependence of the metal-substrate interaction on the cluster size and the role of defects in the nucleation and intercalation processes.

Full textGraphene oxide is a promising nanomaterial thanks to its physicochemical characteristics. However, until today its exact composition remains still unknown. This is due to the complexity and non-stoichiometric character of this material.We started by investigating the surface composition of graphene oxide and its reactivity. We used differently synthesized samples to explore the relationship between the synthesis method and the surface composition. Furthermore, we functionalized graphene oxide with a chelating agent of radionuclides to study its biodistribution, and the impact of the lateral size. Afterwards, we tried different strategies for multifunctionalization with the aim to combine different properties. We observed that the dispersibility of graphene oxide often decreased after functionalization. Thus, we developed a highly water-stable graphene oxide sample by grafting awater-soluble polymer on its surface. Finally, we explored and improved the characterization methods for graphene oxide. Athorough investigation using different characterization techniques is fundamental to understand the modifications that the material underwent

Full textZinc-Oxide (ZnO) has been getting much attention over the past decades because of its potential application in electronic devices and as a catalyst. The structure and reactivity of ZnO surfaces have direct relevance for the performance and functionality of these devices. Therefore, defining and understanding the atomistic details of ZnO surface structures is of particular importance. The atomistic details of ZnO surfaces depend on the preparation procedures. After the crystal preparation, it is necessary to perform a surface characterization, to achieve an improvement in the functionality and efficiency of ZnO-based opto-electronic devices and catalysts. The atomistic perception of the reaction between an organic molecule and ZnO surfaces plays a crucial role in optimizing hydrogen-on-demand delivery in fuel cells, and understanding the atomistic details of adsorption, diffusion, and dissociation of a simple organic molecule paves the way towards unraveling the procedures involved in the hydrogen liberation for fuel cells. In this work, with the aim of enabling structure and stoichiometry determination by using X-ray photoelectron spectroscopy, I present the results of a comprehensive theoretical study on the core-level shifts of ZnO surface reconstructions. Moreover, I provide a thorough investigation of the mixed-terminated (10-10) surface by first examining the conditions under which methanol monolayers can form on this crystal face and by then exploring all possible pathways for its adsorption, diffusion, and initial dehydrogenation. This study provides a comprehensive picture to identify the most probable reaction steps that can be used to interpret experimental findings and will help future theoretical studies for reactions similar to dehydrogenation of organic molecules and monolayer-formation kinetics that were studied here.

Full textIt is well known that a lead pencil is made of graphite, a naturally form of carbon, this is important but not very exciting. The exciting part is that graphite contains stacked layers of graphene and each and every layer is one atom thick. Scientists believed that these graphene layers could not be isolated from graphite because they were thought to be thermodynamically unstable on their own and taking them out from the parent graphite crystal will lead them to collapse and not forming a layer. The question arose, how thin one could make graphite. Two scientists from University of Manchester answered this question by peeling layers from a graphite crystal by using sticky tape and then rubbing them onto a silicon dioxide surface. They managed to isolate just one atom thick layer from graphite for the first time using a method called micromechanical cleavage or scotch tape. In this thesis chemical method also known as Hummers method has been used to fabricate graphene oxide (GO) and reduced graphene oxide. GO was synthesized through the oxidation of graphite to graphene oxide in the presence of concentrated sulphuric acid, hydrochloric acid and potassium permanganate. A strong reducing agent known as hydrazine hydrate has also been used to reduce GO to rGO by removing oxygen functional groups, but unfortunately not all oxygen functional groups have been removed, that is why the final product is named rGO. GO and rGO solutions were then deposited on silicon substrates separately. Several characterization techniques in this work have been used to investigate the optical properties, the morphology, crystallography and vibrational properties of GO and rGO.
