Abstract

In situ SEIRAS analyses revealed a peak shift of adsorbed CO on Pt cocatalysts supported on TiO2 photocatalysts in the presence of sacrificial reagents. This observation suggests that charge separation from the photocatalysts to the cocatalysts was enhanced, leading to negative potential shifts that promote hydrogen evolution.
