Description
Alexia Toumazatou and co-authors boost light-driven catalysis with a built-in optical defect in this 2024 paper. Photonic crystals can slow light to help a catalyst harvest it. The useful slow range is narrow, which caps the gain.
Their film stacks three layers: an inverse opal base, a thin middle sheet, and a photonic top coat. Cobalt oxide clusters on the surface switch the film on under visible light. The middle layer creates a donor-like state inside the band gap, which widens the slow photon range. The tuned film broke down salicylic acid faster and made more photocurrent. Gains beat the sum of single layers.
