dc.description.abstract | In the context of gaining understanding on the origin of the visible-​light photoresponse of TiO2 contg. gold nanoparticles, the photocurrent spectra and photocatalytic H2 evolution of titania (P25) and Au-​P25 were compared. Whereas no photocurrent was detected upon visible-​light irradn. for either of the two photocatalysts, Au-​P25 exhibited photocatalytic H2 evolution for wavelengths between 400 and 575 nm. This contradictory behavior under visible-​light irradn. of Au-​P25 was rationalized by transient absorption spectroscopy. It was suggested that photocatalytic H2 generation results from methanol quenching of the charge-​sepn. state in each semiconductor nanoparticle, but the lack of photocurrent is due to the short lifetime of the charge sepn., which makes interparticle charge migration for micrometric distances unlikely | es_ES |
