Abstract

Metal-organic frameworks (MOFs) are one of the most promising precursors for the fabrication of advanced photocatalysts. In this report, we present a stable in water MOF based on earth-abundant cobalt (Co-BDC) as a highly active catalyst for visible-light-driven H2 generation. The rate of H2 production sensitized by eosin Y (EY) over Co-BDC reached 14.5 mmol g−1 h−1. By in situ addition of graphene oxide suspension to the photocatalytic system, the hydrogen production efficiency was further enhanced by a factor of 6.6.
