Descripción
Au-MxOy (M_Ag, Cu, Ni) nanoparticles supported on TiO2?P25 were prepared by the deposition?precipitation method and were evaluated for the fotocatalytic water splitting reaction for hydrogen production, using a mixture of water-methanol (1:1). The combinations of Au-Cu2O/TiO2 and Au-NiO/TiO2 effectively increased the hydrogen production (2064 and 1636 μmol·h−1·g−1) obtained by Au/TiO2 (1204 μmol·h−1·g−1). The higher photoactivities achieved by Au-Cu2O and Au-NiO nanoparticles deposited on TiO2 were attributed to an enhancement of the electron charge transfer fromTiO2 to the Au-MxOy systems and the effect of surface plasmon resonance of gold nanoparticles.
