Methane Carboxylation Using Electrochemically Activated Carbon Dioxide.

ABSTRACT: Direct synthesis of CH₃ COOH from CH₄ and CO₂ is an appealing approach for the utilization of two potent greenhouse gases that are notoriously difficult to activate. In this Communication, we report an integrated route to enable this reaction. Recognizing the thermodynamic stability of CO₂ , our strategy sought to first activate CO₂ to produce CO (through electrochemical CO₂ reduction) and O₂ (through water oxidation), followed by oxidative CH₄ carbonylation catalyzed by Rh single atom catalysts supported on zeolite. The net result was CH₄ carboxylation with 100 % atom economy. CH₃ COOH was obtained at a high selectivity (>80 %) and good yield (ca. 3.2 mmol g^-1 _cat<
