Bioinspired Molecular Magnetic Field-Responsive Catalyst for On-Demand Switching of 2e− and 4e− Oxygen Reduction

Caption

  • The bioinspired molecular magnetic field responsive catalysts were synthesized to selectively switch between the 2e− and 4e− oxygen reduction reaction (ORR) pathways.
  • The molecular magnetic field responsive catalyst integrated with single domain Fe3O4 delivers a significantly boosted H2O2 selectivity of 63.9% (electron transfer number, n = 2.72), whereas the multi domain Fe3O4 incorporated variant effectively redirects the ORR exclusively toward the 4e− pathw ay (n = 3.67).
