Photocatalytic activity of a 2D copper porphyrin metal-organic framework for visible light overall water splitting.

ABSTRACT: A 2D copper tetrakis(4-carboxyphenyl)porphyrin metal-organic framework has been prepared and used as a photocatalyst for overall water splitting, measuring under visible light irradiation (λ > 450 nm) under one sun power conditions a H₂ production rate of 120 μmol_H2 g_catalyst ^-1 h^-1 that is among the highest ever reported. While the 2D Cu porphyrin MOF undergoes substantial degradation in 3 h upon UV irradiation (320-380 nm) in the presence of air, it appears to be photostable under the conditions of the overall water splitting and visible light exposure, exhibiting similar temporal profiles for H₂ and O₂ evolution. Photocurrent experiments and band energy measurements indicate that the photocata
