Researchers at Kyushu University have developed a photocatalytic system that can selectively capture reacting molecules and hold them close to the active sites that absorb energy from light. This innovation addresses a long-standing challenge of having the photocatalyst maintain a high reaction rate even when the reacting molecules are present at very low concentrations.
