| dc.description.abstract | ABSTRACT: A large number of photocatalytic materials have been studied for water splitting since the seminal work of Fujishima and Honda1, showing great potential for solar energy conversion, including H2 production. The irradiation of a suspension of semiconductor oxides, as is the case of TiO2, presents attracting features but also stringent requirements regarding materials properties, including the tailoring of the electronic structure. Furthermore, efficient charge transport is necessary, as well as effective charge separation and prevention of electron-hole pair recombination, before the redox reactions can proceed2,3. In this work, the catalytic activity under UV excitation of TiO2-Au photocatalyst for H2 production was undertaken using glycerol and ethanol as sacrificial agents. Furthermore, substitution of Au by transition metal Cu was attempted with good results. Comparison is made with results obtained using TiO2-rGO-Pt catalyst under analogous loading conditions. | pt_PT |
