Antibiotic resistance has become a global problem as indicated by the worldwide emergence of multidrug-resistant bacteria, which makes it an urgent demand to develop effective technologies for antibiotics removal from pharmaceutical wastewater. In this work, simultaneously removing antibiotic tetracycline from wastewater coupled with pure H₂ generation has been successfully achieved through PEC technique by using F-doped BiVO₄@NiFe-LDH (F-BiVO₄@NiFe-LDH) core-shell photoanode. The maximum photocurrent density of the F-BiVO₄@NiFe-LDH photoanode at 1.23 V vs. RHE is about 6-fold that of the pristine BiVO₄ photoelectrode. Furthermore, the composite photoanode was effectively applied to the PEC degradation of tetracycline hydrochloride (TCH), superior to the reported results. An experimental-computational combination study reveals that the synergistic effect between F doping and NiFe-LDH simultaneously improves the light absorption, charge separation and charge injection efficiency of BiVO₄. This work presents a sunlight-driven, efficient and sustainable method for water splitting to produce hydrogen and new insights into wastewater treatment.

正如世界范围内出现的多药耐药细菌所表明的那样，对抗生素的耐药性已成为一个全球性问题，这迫切需要开发有效的技术来从制药废水中去除抗生素。在这项工作中，通过使用F掺杂的BiVO ₄ @ NiFe-LDH（F-BiVO ₄ @ NiFe-LDH）核壳光电阳极，通过PEC技术成功地实现了从废水中同时去除抗生素四环素和纯H _2的产生。F-BiVO ₄ @ NiFe-LDH光电阳极在1.23 V vs. RHE时的最大光电流密度约为原始BiVO _4的6倍光电极。此外，复合光阳极可有效应用于四环素盐酸盐（TCH）的PEC降解，优于已报道的结果。实验与计算的组合研究表明，F掺杂与NiFe-LDH的协同作用可同时提高BiVO ₄的光吸收，电荷分离和电荷注入效率。这项工作提出了一种阳光驱动，高效且可持续的水分解方法，以产生氢气，并为废水处理提供了新见解。
