AI Article Synopsis
- A new composite material has been developed that combines silver nanoparticles with three-dimensional organic cages made of light-absorbing porphyrins, which help stabilize the particles and capture small molecules.
- The interaction between the porphyrins and the silver nanoparticles enhances energy transfer, with time-resolved spectroscopy showing up to 37% of excited energy being transferred to the porphyrin layer.
- This innovative setup significantly improves the efficiency of photoelectrochemical water-splitting processes and shows potential for future applications in photocatalysis and sensing.
Article Abstract
We report a new composite material consisting of silver nanoparticles decorated with three-dimensional molecular organic cages based on light-absorbing porphyrins. The porphyrin cages serve to both stabilize the particles and allow diffusion and trapping of small molecules close to the metallic surface. Combining these two photoactive components results in a Fano-resonant interaction between the porphyrin Soret band and the nanoparticle-localised surface-plasmon resonance. Time-resolved spectroscopy revealed the silver nanoparticles transfer up to 37 % of their excited-state energy to the stabilising layer of porphyrin cages. These unusual photophysics cause a 2-fold current increase in photoelectrochemical water-splitting measurements. The composite structure provides a compelling proof of concept for advanced photosensitiser systems with intrinsic porosity for photocatalytic and sensing applications.
