摘要

2,4-二氯苯氧乙酸（2,4-D）是一种农用化学品，用于清除稻田中的杂草。由于其毒性，含有 2,4-D 的水需要进行处理。因此，本文利用牛尿进行绿色合成，制备了一种阳光响应型 ZrO2-Bi2O3 光催化剂，并测试了其降解 2,4-D 的效率。然后对制备的 ZrO2-Bi2O3 进行了详细表征。实验结果表明，40% ZrO2-Bi2O3 的光催化活性最好，即使重复使用五次也很稳定。此外，采用新开发的 "基于权重的排序法 "对所研究技术的可持续性进行了分析，结果表明本研究涉及到 17 个可持续发展目标中的 14 个目标。

The 2,4-dichlorophenoxyacetic acid (2,4-D) is an agrochemical used to remove weeds in paddy fields. Due to the toxicity associated, 2,4-D containing water needs treatment. Thus, herein, a sunlight-responsive ZrO₂-Bi₂O₃ photocatalyst was prepared by green synthesis using cow urine and tested for its efficiency in degrading 2,4-D. The prepared ZrO₂-Bi₂O₃ was then characterized in detail. The experimental results showed that 40% ZrO₂-Bi₂O₃ showed the best photocatalytic activity and stable even after five cycles of reuse. Furthermore, the sustainability of the studied technique that was analysed by the newly developed “weightage-based ranking method” showed that the present work addressed 14 of 17 SDGs.
