Asymmetric Co2+–Ov–Co3+ Sites With Strong d–π* Interactions for Activating Nitrogen Toward Photocatalytic Ammonia Synthesis
Solar‐driven photocatalytic nitrogen reduction reaction (p‐NRR) offers a sustainable pathway for ammonia synthesis under ambient conditions. However, its efficiency is fundamentally hampered by the kinetic inertness of the N≡N triple bond. Herein, we construct oxygen‐vacancy‐induced asymmetric Co2+–Ov–Co3+ units within...
