Constructing sulfur and oxygen super-coordinated main-group electrocatalysts for selective and cumulative H₂O₂ production.

ABSTRACT: Direct electrosynthesis of hydrogen peroxide (H₂O₂) via the two-electron oxygen reduction reaction presents a burgeoning alternative to the conventional energy-intensive anthraquinone process for on-site applications. Nevertheless, its adoption is currently hindered by inferior H₂O₂ selectivity and diminished H₂O₂ yield induced by consecutive H₂O₂ reduction or Fenton reactions. Herein, guided by theoretical calculations, we endeavor to overcome this challenge by activating a main-group Pb single-atom catalyst via a local micro-environment engineering strategy employing a sulfur and oxygen super-coordinated structure. The main-group catalyst, synthesized using a carbon dot-assisted pyrolysis technique, d
