Abstract

Oxygen reduction reaction (ORR) for generating H₂O₂ through green pathways have gained much attention in recent years. Herein, we introduce a piezo-catalytic approach to obtain H₂O₂ over bismuth oxychloride (BiOCl) through an ORR pathway. The piezoelectric response of BiOCl was directly characterized by piezoresponse force microscopy (PFM). The BiOCl exhibits efficient catalytic performance for generating H₂O₂ (28 μmol h⁻¹) only from O₂ and H₂O, which is above the average level of H₂O₂ produced by solar-to-chemical processes. A piezo-catalytic mechanism was proposed: with ultrasonic waves, an alternating electric field will be generated over BiOCl, which can drive charge carriers (electrons) to interact with O₂ and H₂O, then to form H₂O₂.
