Key Points

Design and investigate phosphorus-mediated copper-nitrogen active sites supported on carbon nitride for selective photocatalytic conversion of carbon dioxide to ethylene.
Synthesized carbon nitride frameworks embedding phosphorus-tuned copper-nitrogen (Cu-N4) single-atom coordination centers.
Characterized catalyst architecture and monitored solar-driven carbon dioxide photoreduction activity and hydrocarbon product distribution.
Promoted the selective photoreduction of carbon dioxide to ethylene over single-carbon byproducts.
Phosphorus modification tailored electron distribution at the copper coordination sites, stabilizing carbon-carbon coupling intermediates during photoreduction.
