    "body_text": "Chinese Academy of Sciences researchers tracked single copper atoms on titanium dioxide while the material photoreduced carbon dioxide to carbon monoxide. In-situ spectroscopy indicated that the copper and neighboring titanium sites change roles under illumination and cooperate during the reaction rather than acting as a fixed center. The mechanistic study explains a laboratory catalyst; it does not establish industrial carbon removal or energy efficiency.",
