AI Summary

Researchers at Kyushu University created a photocatalytic system that uses a counteranion to capture reacting molecules and keep them near the light‑absorbing active sites. By holding reactants close to the excited photocatalyst, the design maintains high reaction rates even when the reactants are present at very low concentrations. The approach tackles the typical slowdown in photocatalysis caused by fewer collisions between dilute molecules and the energized catalyst. This method could improve the efficiency of light‑driven chemical processes that otherwise require high temperatures.
