Ferromagnetic Fe-TiO₂ spin catalysts for enhanced ammonia electrosynthesis.

ABSTRACT: Magnetic field effects (MFE) of ferromagnetic spin electrocatalysts have attracted significant attention due to their potential to enhance catalytic activity under an external magnetic field. However, no ferromagnetic spin catalysts have demonstrated MFE in the electrocatalytic reduction of nitrate for ammonia (NO₃RR), a pioneering approach towards NH₃ production involving the conversion from diamagnetic NO^3- to paramagnetic NO. Here, we report the ferromagnetic Fe-TiO₂ to investigate MFE on NO₃RR. Fe-TiO₂ possesses a high density of atomically dispersed Fe sites and exhibits an intermediate-spin state, resulting in magnetic ordering through ferromagnetism. Assisted by a magnetic field, Fe-TiO₂ achieves
