Abstract:

Gold supported titania nano-particle surfaces have been synthesised in order to understand supported electrochemical mechanisms through an inverse catalyst. The catalyst process investigated was the electro-oxidation of CO which is known to be promoted on Au nano-particles on a titania support. Synthesis proceeded via physical vapour deposition (PVD) of titanium onto a gold surface (both polycrystalline and 111 crystal), followed by alloying and oxidation to form discrete particles of titania on the surface, with variations in density of particles achieved by control of the initial titanium co

Abstract:

Direct methanol fuel cells (DMFCs) are considered a clean source of electrical power for future energy demand, creating a potential to reduce our dependency on fossil fuels. Despite their advantages, including high energy density, efficiency and easy handling and distribution of fuel, the commercialization of DMFCs has suffered from some drawbacks, including methanol crossover and contamination of the system. Metal cation contaminants (such as Ni, Co, etc) introduced through the degradation of fuel cell components (bipolar plate and electro-catalyst layer) can significantly affect the Nafion-m

The main focus was put on the grafting of intrinsically soluble substituted regioregular polyalkylthiophenes because of their excellent optoelectronic properties. The resulting polymer films were characterized and their optoelectrical properties studied.

Il processo di riduzione dell'anidride carbonica (CO2) ha suscitato negli ultimi anni grande attenzione nella comunità scientifica. Lo sviluppo di materiali e sistemi in grado di convertire H2O e CO2 in prodotti ad alto valore utilizzando energia rinnovabile e pulita, rappresenta una sfida particolarmente attraente per il prossimo futuro. In questo contesto, lo scopo del presente lavoro di Dottorato è stato quello di valutare diversi approcci, tra cui quelli foto- ed elettrocatalitici, per convertire la CO2 in sostanze chimiche e combustibili a più alto valore aggiunto.
