摘要

分子掺杂聚（3-己基噻吩）（P3HT）首次被用作将氧气还原成 H2O2 的光电阴极。为此，在 P3HT 薄膜中掺入了六氮三苯基六甲腈，从而增加了在黑暗中施加负电位时的氧还原电流。用可见光照射掺杂的 P3HT 薄膜可显著促进高电流密度的氧还原，并使起始电位超过反应平衡电位。本文结合能级图讨论了掺杂 P3HT 薄膜的氧还原性能。

Molecularly doped polythiophene film as an efficient photocathode for oxygen reduction to hydrogen peroxide

The molecularly doped poly(3-hexylthiophene) (P3HT) was used for the first time as a photocathode for reducing oxygen to H₂O₂. For this purpose, a P3HT film was doped with hexaazatriphenylenehexacarbonitrile, which increased the oxygen reduction current at an applied negative potential in the dark. Visible light illumination of the doped P3HT film significantly facilitated the oxygen reduction with a high current density and shifted the onset potential beyond the reaction equilibrium potential. The oxygen reduction performance of the doped P3HT film is discussed in relation to the energy level diagram.
