IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

The PhD project focused on the synthesis, characterisation and testing of metal modified TiO2 powders and thin WO3 films for solar energy conversion and photocatalytic oxidation reactions. In the first part, two industrial processes, i.e. Flame Spray Pyrolysis and Magnetron Sputtering, were employed to modify TiO2 powders with Cu and/or Pt nanoparticles. These photocatalysts were tested in the methanol photosteam reforming reaction for hydrogen production. The most promising materials were further tested in the same reaction at different temperatures to observe the effect of heat over photoactivity and selectivity. In addition, ME-XAS analyses were performed to better understand the behaviour of metal nanoparticles over TiO2 under operando conditions. In the second part, WO3 films were synthesised by sputtering techniques and the effect of several deposition parameters, such as total pressure, O2 partial pressure, applied power, number of deposited layers, were investigated by means of photo-electrochemical techniques.
