Abstract

α‐Fe2O3/NiCoFe–OH photoelectrode with high hydrophilicity is obtained by hot alkali etching on the surface of α‐Fe2O3/NiCoFe–LDH. Compared with α‐Fe2O3/NiCoFe–LDH (CO3(OH)16·4H2O), α‐Fe2O3/NiCoFe‐OH photoelectrodes with high hydrophilicity show better photocurrent performance. This improvement is attributed to the highly hydrophilic NiCoFe–OH promoting effective contact between the photoelectrode and the electrolyte, thus enhancing effective carrier separation and migration on the electrode. In these findings, an effective way is provided to improve the photoelectrochemical properties of α‐Fe2O3.

高亲水性 NiCoFe-OH 可加速电荷界面转移并增强 α-Fe2O3 的光电化学特性

通过在 α-Fe2O3/NiCoFe-LDH 表面进行热碱蚀刻，获得了具有高亲水性的 α-Fe2O3/NiCoFe-OHoe 光电极。与 α-Fe2O3/NiCoFe-LDH (CO3(OH)16-4H2O)相比，高亲水性 α-Fe2O3/NiCoFe-OH 光电极具有更好的光电流性能。这种改善归因于高亲水性 NiCoFe-OH 促进了光电极与电解质之间的有效接触，从而提高了载流子在电极上的有效分离和迁移。这些发现为改善 α-Fe2O3 的光电化学特性提供了一种有效的方法。
