Abstract

We used Erythrosin B dye to sensitize Zr-containing MOFs of UiO-66 octahedrons for photocatalytic H₂ production. No H₂ production was observed over Pt-loaded UiO-66 octahedrons under visible light irradiation. Comparatively, efficient hydrogen production was achieved upon visible light irradiation in this dye sensitized MOFs system. The highest H₂ production rate of 4.6μmolh^-1, corresponding to 0.25% quantum efficiency at 420nm, occurs from the system containing 10mg MOFs photocatalyst and 30mg Erythrosin B dye. The enhancement in photocatalytic H₂ production was benefited from the efficient charge transfer from photoexcited Erythrosin B dye to the MOFs. Owing to the advantages of low cost, easy operation, and abundance in nature, the dye sensitized MOFs shows great potential for photocatalytic H₂ production.
