Abstract

The Ni/NiO_x particles were in situ photodeposited on MIL-101 metal organic frameworks as catalysts for boosting H₂ generation from Erythrosin B dye sensitization under visible-light irradiation. The highest H₂ production rate of 125 μmol h^-1 was achieved from the system containing 5 wt. % Ni-loaded MIL-101 (20 mg) and 30 mg Erythrosin B dye. Moreover, the Ni/NiO_x catalysts show excellent stability for long-term photocatalytic reaction. The enhancement on H₂ generation is attributed to the efficient charge transfer from photoexcited dye to the Ni catalyst via MIL-101. Our results demonstrate that the economical Ni/NiO_x particles are durable and active catalysts for photocatalytic H₂ generation.
