Highly Efficient Visible-Light-Driven H2 Production via an Eosin Y-Based Metal-Organic Framework.

A simple and effective strategy was developed to immobilize ecofriendly dye inside a porous metal–organic framework (MOF) built from Eosin Y with [Cd2(COO)2(μ2-H2O)] secondary building units for the first time. The MOF exhibited efficient photocatalytic activity for H2 evolution under visible-light irradiation with a turnover number of 13920 and an initial turnover frequency of 7433 h–1, which was approximately 31 times the photocatalytic efficiency of Eosin Y.
