Zn-Schiff Base Polymer Electrocatalytic H2O2 Generation: Mechanistic Insights from In Situ Spectroscopy

The production of H₂O₂ via the two-electron pathway of ORR has been widely studied. We pioneered the use of a Zn-Schiff base conductive polymer nanorod as an electrocatalyst for H₂O₂ production, leveraging the Schiff base's ability to enhance electron transfer and catalytic efficiency. This novel catalyst achieved an unprecedented >98% H₂O₂ selectivity with >90% stability after 1000 h. In situ DRIFTS, in situ SERS, and theoretical calculations confirm the Schiff base's critical role in optimizing electron transfer for superior H₂O₂ generation.
