Low-coordinated CuNi dual-atom catalyst for efficient flue gas CO 2 -to-C 2 H 6 photoreduction

Nature Communications, Published online: 21 August 2026; doi:10.1038/s41467-026-77025-x CuNi/PCN with low-coordinated N3-Ni-Cu-N2 dual-atom sites achieves selective C2H6 production with a 1.15% AQE in dilute flue gas CO2. Synergistic dual sites promote C-C coupling and endow the catalyst with strong resistance to NOx and SO2 poisoning.
