Photocatalytic hydrogen production of porphyrin nanostructures: spheres vs. fibrils, a case study

Herein, we illustrate the preparation of a covalent connected peptide-porphyrin hybrid (Fmoc-FF-(Zn)Por). The thorough investigation of its self-organization features demonstrated that Fmoc-FF-(Zn)Por self-assembles into either spheres or fibrils by altering the solvent mixture. Interestingly, photocatalytic hydrogen (H-2) evolution experiments revealed that fibrils were more efficient towards H-2 production compared to spheres.

Automated summary

In this study, a covalently connected peptide-porphyrin hybrid was prepared and found to self-assemble into either spheres or fibrils depending on the solvent mixture. Photocatalytic hydrogen evolution experiments showed that fibrils were more efficient in H-2 production compared to spheres.
