Abstract
- The direct co-conversion of methane and carbon dioxide into valuable chemicals has been a longstanding scientific pursuit for carbon neutrality and combating climate change. Herein, we present a photo-driven chemical process that reforms these two major greenhouse gases together to generate green methanol and CO, two high-valued industrial chemicals. Isotopic labeling and control experiments indicate an oxygen-atom-graft occurs, wherein CO<subscript>2</subscript> transfers one O into the C–H bond of CH<subscript>4</subscript> via photo-activated interfacial catalysis with AuPd nanoparticles supported on GaN. The photoexcited AuPd/GaN interface effectively orchestrates the CH<subscript>4</subscript> oxidation and the CO<subscript>2</subscript> reduction producing 13.66 mmol g<superscript>−1</superscript> of CH<subscript>3</subscript>OH yield over 10 h. This design provides a solid scientific basis for the photo-driven oxygen-atom-grafting process to be further extended to visible light region. The direct co-conversion of CH<subscript>4</subscript> and CO<subscript>2</subscript> into valuable chemicals has been a longstanding scientific pursuit. Here, the authors present a photo-driven process that reforms these greenhouse gases together to generate CH<subscript>3</subscript>OH and CO over AuPd/GaN. [ABSTRACT FROM AUTHOR]
