Optimized Carbon Coupling for Enhanced Ethylene Production via a Unique Single‐Atom‐Substrate Synergy Mechanism within Photocatalytic Processes
The utilization of solar-driven technologies for the direct conversion of methanol (CH<sub>3</sub>OH) into two or multi-carbon compounds through controlled carbon-carbon (C-C) coupling is an appealing yet challenging objective. In this study, we successfully demonstrate the photocatalytic CH<sub>3</sub>OH coupling to ethylene (C<sub>2</sub>H<sub>4</sub>), a valuable chemical raw material, by employing a carbon nitride-based catalyst. Specifically, we modify the layered polymer carbon nitride (PCN) photocatalyst through the incorporation of Au single atoms (Au<sub>1</sub>/PCN) using a chemical-scissors method. The synergistic effect between the PCN substrate and the Au single atoms reduces the potential barrier associated with C-C coupling, thereby enhancing the efficiency of CH<sub>3</sub>OH reforming to C<sub>2</sub>H<sub>4</sub>. This investigation not only reveals a novel pathway for C<sub>2</sub>H<sub>4</sub> production via CH<sub>3</sub>OH reforming but also provides fresh insights into the possibilities of C-C coupling.
