The scarcity of pure water has become a global and major concern because of rapid industrialization in modern and exponentially populated civilization. No life can exist without water, and contamination-free water for the whole ecosystem is a primary demand. Therefore, the enhanced rate of water contamination and the infliction of living beings are considered to be challenging issues. It attracts great attention in the scientific community when water pollution by multifarious endocrine disruptors (EDs) such as plasticizers, herbicides, insecticides, pharmaceutical and personal care products, and food additives and sweeteners, which are discharged from industries, reach water resources, and finally appear in drinking water, is involved. The chemical contaminants of EDs disturb the functions of glands from where hormones or juices are secreted and mix with blood directly. Their persistence results in adverse toxic effects in all living beings, for example, declining reproduction, endometriosis, cancer, and many more diseases. These are not easily mineralized or removed from water compared to various organic dye molecules because of their typical characteristic light absorption in the UV region. Therefore, it is very urgent to mineralize wastewater from such types of contaminants. Among the existing technologies, visible-light-triggered photocatalytic degradation is accredited as cost-effective, renewable, and environmentally friendly. Besides, the utilization of cheap visible light as a driving force with strong mineralization efficiency under facile reaction conditions and no harmful end products enables it to have a more beneficial effect. This review describes different classes of EDs, their adverse toxic effects, and efficient degradation through remarkable active nanomaterials/nanocomposites reported from 2015 to 2020. The detailed mechanisms of pollutant adsorption on the nanostructure surface and their decomposition actions have been interpreted. Also, different pollutant degradation pathways have been attentively considered and well-explained. Besides, the future outlook has been elucidated at the end.

使用可见光活性纳米结构对水中内分泌干扰物进行解毒的研究进展

由于现代和成千上万人口文明的迅速工业化，纯水的稀缺已成为全球和主要关注的问题。没有水就不可能有生命，整个生态系统的无污染水是主要需求。因此，水污染的增加率和对生物的侵害被认为是具有挑战性的问题。当工业排放的多种内分泌干扰物（ED）（例如增塑剂，除草剂，杀虫剂，药品和个人护理产品以及食品添加剂和甜味剂）对水的污染最终引起科学界的高度关注时，这些污染物已从工业中排放出来，到达了水资源，最后出现在饮用水中，参与其中。EDs的化学污染物扰乱了分泌激素或汁液并直接与血液混合的腺体的功能。它们的持久性会对所有生物产生不利的毒性作用，例如，生殖能力下降，子宫内膜异位症，癌症以及许多其他疾病。与各种有机染料分子相比，它们不容易矿化或从水中去除，因为它们在紫外线区域的典型特征是光吸收。因此，迫切需要从这类污染物中使废水矿化。在现有技术中，可见光触发的光催化降解被认为具有成本效益，可再生且对环境友好。除了，利用廉价的可见光作为驱动力，在容易的反应条件下具有强大的矿化效率，并且没有有害的最终产物，使其具有更有利的作用。这篇综述描述了2015年至2020年报告的不同类型的ED，其不良的毒性作用以及通过显着的活性纳米材料/纳米复合材料的有效降解。已经解释了污染物在纳米结构表面的吸附及其分解作用的详细机理。另外，已经仔细考虑并充分说明了不同的污染物降解途径。此外，最后的前景已经阐明。并在2015年至2020年期间通过出色的活性纳米材料/纳米复合材料有效降解。对污染物在纳米结构表面的吸附机理及其分解作用进行了详细解释。另外，已经仔细考虑并充分说明了不同的污染物降解途径。此外，最后的前景已经阐明。并在2015年至2020年间通过出色的活性纳米材料/纳米复合材料有效降解。对污染物在纳米结构表面的吸附机理及其分解作用进行了详细解释。另外，已经仔细考虑并充分说明了不同的污染物降解途径。此外，最后的前景已经阐明。
