WebbThis study demonstrates that photocatalytic performance of TiO 2 –NAA-DBRs is enhanced by the “slow photon” effect when the edges of the PC’s photonic stopband (PSB) fall within the absorbance band of the organic molecules. Webb13 mars 2024 · The experimental results show that the slow photon effect and the narrow band gap caused by the bulk oxygen vacancy greatly improve the light harvesting efficiency, and the abundant surface oxygen vacancy can reduce the valence band as well as increase the power of water oxidation, thus significantly promoting the separation of …
Webb1 feb. 2024 · The slow photon effect enhances photocatalytic H 2 production with ∼1.4× and 1.7× at the red and blue edges respectively, providing direct experimental evidence that the slow photon effect occurring at the blue edge can bring a higher photocatalytic … WebbPhotonic crystals have been widely used in solar cells in recent years because of their unique optical properties such as photonic band gap and “slow photon” effect. [2] Compared with a disorderly stacked ZnO film, the ZnO PC film shows a higher activity in …
Webbreactions. “Slow photon” effect occurs at the frequency edges of the PSB, where slow photons (i.e. photons with strongly reduced group velocity) are primarily localized in the high (i.e. red edge of the PSB) and low (i.e. blue edge of the PSB) dielectric parts of the … WebbThe synergy of the slow photon effect and hierarchically porous structure of inverse opal itself results in the highest photocatalytic activity at an incident light angle of θ = 40°. Moreover, our results suggest that the slow photon effect occurring at the red edge of …
