A pure organic heterostructure of μ-oxo dimeric iron(III) porphyrin and graphitic-C3N4 for solar H2 roduction from water

Due to the two-dimensional flexible structure and abundant pendant amine, graphitic-C3N4 (g-C3N4) may be easily modified by organic molecules as a promising photocatalyst for solar H-2 production from water. Here, through a simple liquid chemical reaction between g-C3N4 and the precursor of m-oxo dimeric iron(III) porphyrin [(FeTPP)(2)O], we provide a novel route to construct a pure organic heterostructure of g-C3N4/(FeTPP)(2)O on the basis of the pi-pi and the Fe-amine interactions. The experimental results demonstrated that (FeTPP)(2)O acted not just as a photosensitizer, but also played the role of a charge promotor to prohibit the recombination of the excited electrons and holes of g-C3N4. As compared to pure or mixed g-C3N4 and/or (FeTPP)(2)O, the obtained pure organic g-C3N4/(FeTPP)(2)O heterostructure exhibited dramatic photocatalytic H-2 production under solar light without any cocatalysts.
