Slow Photon-induced Enhancement of Photocatalytic Activity of Gold Nanoparticle-incorporated Titania Inverse Opal

Here, we report a novel structured material, titania inverseopal photonic crystal with or without a single gold nanoparticle in each void, to provide a photoabsorption design strategy as enhanced photoreaction rates, only when wavelengths of photo-irradiation, photoabsorption (by gold nanoparticles or titania), and photonic-bandgap edge are trebly matched.

Automated summary

This study presents a novel structured material, titania inverse-opal photonic crystal, with or without a single gold nanoparticle in each void, offering a photoabsorption design strategy for enhanced photoreaction rates. This strategy is effective only when the wavelengths of photo-irradiation, photoabsorption, and photonic-bandgap edge are all matched.
