Energy-saving and product-oriented hydrogen peroxide electrosynthesis enabled by electrochemistry pairing and product engineering.

ABSTRACT: Hydrogen peroxide (H₂O₂) electrosynthesis through oxygen reduction reaction (ORR) is drawing worldwide attention, whereas suffering seriously from the sluggish oxygen evolution reaction (OER) and the difficult extraction of thermodynamically unstable H₂O₂. Herein, we present an electrosynthesis protocol involving coupling ORR-to-H₂O₂ with waste polyethylene terephthalate (PET) upcycling and the first H₂O₂ conversion strategy. Ni-Mn bimetal- and onion carbon-based catalysts are designed to catalyze ORR-to-H₂O₂ and ethylene glycol electrooxidation with the Faradaic efficiency of 97.5% (H₂O₂) and 93.0% (formate). This electrolysis system runs successfully at only
