Magneto-voltaic activity of single-atom iron on reduced graphene oxide for magneto-catalytic conversion of H₂O₂ into O₂.

ABSTRACT: Recent advances in magnetically enhanced (electro)catalysis have disclosed the potential of magnetic fields to modulate reaction kinetics and catalytic performance. Herein, a combination of alternating magnetic field (AMF) as a physical stimulus, reduced graphene oxide (rGO) as a magneto-sensitizer, single-atom Fe on rGO (FeSA:rGO) as the catalytic active site, and H₂O₂ as a dual reductant and oxidant demonstrated a proof-of-concept magneto-catalytic process that is thermodynamically driven solely by magneto-voltaic activity. Upon application of an AMF to electroconductive FeSA:rGO, AMF-induced charge separation led to formation of low-lying electron holes (E _HOMO = 2.41/2.43 eV) and excited electrons (E _LUMO = -0.65/-0.57 eV), whic
