Self-Assembly of Metalloporphyrins into Light-Harvesting Peptide Nanofiber Hydrogels for Solar Water Oxidation

Artificial light‐harvesting nanofiber hydrogels are successfully synthesized by the self‐assembly of Fmoc‐FF peptides and metalloporphyrins. The metalloporphyrins are placed in close enough proximity to each other to enable excited energy transfer, increasing the photosensitization efficiency, as ob...

Description
Summary:Artificial light‐harvesting nanofiber hydrogels are successfully synthesized by the self‐assembly of Fmoc‐FF peptides and metalloporphyrins. The metalloporphyrins are placed in close enough proximity to each other to enable excited energy transfer, increasing the photosensitization efficiency, as observed in natural light‐harvesting complexes in green plants. The metalloporphyrins in the light‐harvesting hydrogel increase the efficiency of photocatalytic water oxidation by iridium oxide nanoparticles up to approximately 3.7 times compared to their physical mixture.
