摘要

通过ORR的双电子途径生产H2O2已被广泛研究。我们率先使用锌-希夫碱导电聚合物纳米棒作为生产H2O2的电催化剂，利用希夫碱增强电子转移和催化效率的能力。这种新型催化剂在1000小时后实现了前所未有的>98%的H2O2选择性和>90%的稳定性。原位漂移、原位SERS和理论计算证实了希夫碱在优化电子转移以获得卓越的H2O2生成方面的关键作用。

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.

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
