Abstract

Efficient photocatalytic hydrogen evolution is obtained from 1 M phosphate buffer at pH 7 in the presence of a Ru (bpy) 32+ sensitizer, an ascorbic acid sacrificial donor, and a water- soluble Co (II) porphyrin catalyst. Spectroscopic investigation of the system by stationary and time-resolved techniques enables a complete characterization of the photoinduced dynamics.
