Abstract Light‐driven greenhouse gases upgrading (GGU) into syngas is a promising approach to reduce CO 2 emissions and supply green fuels simultaneously. However, this reaction usually suffers from high operation temperature low conversion rate due stringent thermodynamic constraints. Herein, selective plasmonic CH bond editing strategy presented via incorporating ultralow amounts of Cu Ni‐based catalysts by electrostatic adsorption. A remarkable 2.69 times as the limit extraordinary light‐to‐fuel efficiency 24.95% at 500 °C are achieved, outperforming state‐of‐the‐art literature reports. The extremely fraction (0.06 wt%) assists injection localized surface plasmon resonance induced hot electrons antibonding orbital reactants, accelerating cleavage first * CH 4 , which rate‐determining step for GGU. Simultaneously, intermediates proceed along CH+ O = CHO rather than C+ H, thus avoid complete subsequent coke deposition, leading stable on‐stream over 20 h. Such enables ordered with synergistically beyond limits.

Abstract The C−C coupling of methane (CH 4 ) and carbon dioxide (CO 2 to generate acetic acid 3 COOH) represents a highly atom‐efficient chemical conversion, fostering the comprehensive utilization greenhouse gases. However, inherent thermodynamic stability kinetic inertness CH CO present obstacles achieving efficient selective conversion at room temperature. Our study reveals that hydroxyl radicals (⋅OH) hydrated electrons (e aq − produced by water radiolysis can effectively activate , yielding methyl (⋅CH radical anions(⋅CO facilitate production COOH ambient introduction radiation‐synthesized CuO‐anchored TiO bifunctional catalyst could further enhance reaction efficiency selectivity remarkably boosting radiation absorption stability, resulting in concentration 7.1 mmol ⋅ L −1 with near‐unity (>95 %). These findings offer valuable insights for design implementation radiation‐induced conversion.
