AI Summary (NQ-processed)
A research group from Chiba University and the Chengdu Institute of Biology has clarified the distinct roles of light-generated electrons and hot spots in the photocatalytic conversion of CO₂ to methane. They developed a novel Ni–Ru–ZrO₂ catalyst that achieves world-leading CO₂ photo-methanation rates, demonstrating that Ru addition facilitates CO₂ adsorption, allowing the reaction to proceed via light-induced heating. This breakthrough offers critical guidance for developing highly efficient CO₂ photoreductive catalysts.
