Efficient electroreduction of CO₂ to C₁ and C₂ products using atomically dispersed boron N-C@graphite catalysts.

ABSTRACT: Atomically precise control of active sites is essential for advancing metal-free electrocatalysts for the CO₂ reduction reaction (CO₂RR). We report boron- and nitrogen-co-doped graphite (boron-N-C@graphite) derived from chloro-boron subphthalocyanine (Cl-B-SubPc), an aromatic macrocyclic precursor that directs simultaneous incorporation of B and N into conductive carbon frameworks. X-Ray photoelectron spectroscopy reveals the formation of B-C and B-N motifs alongside pyridinic and graphitic N, generating electron-deficient centers that modulate intermediate binding energies. The resulting catalysts display pronounced structure-activity correlations: pyrolysis at 800 °C favors formate and acetate formation, whereas 1000 °C yields a more graphitic catalyst with enhanced
