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 (<i>E</i> _HOMO = 2.41/2.43 eV) and excited electrons (<i>E</i> _LUMO = -0.65/-0.57 eV), whicChemical scienceMagneto-voltaic activity of single-atom iron on reduced graphene oxide for magneto-catalytic conversion of H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; into O&lt;sub&gt;2&lt;/sub&gt;.PMC12628007110-2622-M-007-002112-2628-M-007-004-MY4114-2218-E-007-012109Q2711E1109-2622-M-007-003-CC2113-2218-E-007-014109-2628-M-007-003-MY3110Q2513E1Chen CLLai YCChi CCHuang CCChen HTDhanthala Chittibabu DKChen YCLu MYApfel UPLiang JGIffland LChen JLChan TSChung CWHuang JYLu TTLu YRLin ZHDayao LAChou HHfalseMagneto-voltaic activity of single-atom iron on reduced graphene oxide for magneto-catalytic conversion of H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; into O&lt;sub&gt;2&lt;/sub&gt;.Recent advances in magnetically enhanced (electro)catalysis have disclosed the potential of magnetic fields to modulate reaction kinetics and catalytic performance.
