Abstract

In this work, an iodine vacancy-modulated dual S-scheme BiOI/BiSI/BiOBr heterojunction was prepared via a hydrothermal method, and its photocatalytic efficiency was assessed through the degradation of tetracycline hydrochloride (TCH). The results reveal that the combined effects of improved visible light absorption, iodine vacancies, S-scheme charge transfer, and electron sacrificial agent significantly enhance photocatalytic activity. Under visible light irradiation for 240 min, the BiOI/BiSI/BiOBr heterojunction achieves an impressive TCH degradation rate of 89.51 %, which is approximately 2.06 times higher than that of BiOBr. Additionally, the heterojunction remains stable throughout the photocatalytic process as long as surface-adsorbed TCH is removed with deionized water and anhydrous ethanol after each cycle. The anion vacancy-modulated dual S-scheme charge transfer offers valuable insights into the photocatalytic oxidation of contaminants.

碘空位调制双S-scheme BiOI/BiSI/BiOBr异质结增强盐酸四环素降解的制备
本文采用水热法制备了碘空位调制的双S-scheme BiOI/BiSI/BiOBr异质结,并通过对盐酸四环素(TCH)的降解评价了其光催化效率。结果表明,改善可见光吸收、碘空位、S-scheme电荷转移和电子牺牲剂的共同作用显著提高了光催化活性。在可见光照射240 min下,BiOI/BiSI/BiOBr异质结的TCH降解率达到89.51%,是BiOBr的2.06倍。此外,只要在每个循环后用去离子水和无水乙醇去除表面吸附的TCH,异质结在整个光催化过程中保持稳定。阴离子空位调制的双s方案电荷转移为污染物的光催化氧化提供了有价值的见解。
