Single-atom Ru coupled with AlCl₃ to promote asymmetric C-C coupling between CH₄ and CO₂.

ABSTRACT: Direct synthesis of acetic acid from CH₄ and CO₂ offers a sustainable strategy to utilize these byproducts co-existed in many anthropogenic scenarios with 100% atom efficiency and mitigate greenhouse effect. But this reaction remains a grand challenge due to chemical inertness of two reactants and sluggish kinetics of C-C coupling. Herein, we propose a bifunctional catalyst design, consisted of metal and Lewis acid, to activate CH₄ and CO₂ via nucleophilic and electrophilic attacks, respectively, which generating two intermediates with opposite electron properties and promote asymmetric C-C coupling. To achieve this, a rational design with "six-step" screening predicts an efficient catalyst, i.e., Keggin-type phosphotungstic acid supporting equim
