Conventional Fe-based catalysts suffer from strong Fe–N bonds that limit ammonia desorption. Now an AlFe dual-site catalyst is shown to circumvent this limitation by forming weakly bonded Al–N species via a photoinduced nitrogen spillover mechanism, achieving an ammonia synthesis rate of 8.6 mmol gcat−1 h−1 at 4.28 W cm−2.
