: Synthetic dyes are utilized across a variety of industries and pose potential threats to water quality which, adversely, affects human health and environment. Photocatalysis is an effective technique for degrading organic pollutants in wastewater by converting photons of light energy to chemical energy by using superior semiconducting materials. Herein, we emphasized the significance of wastewater treatment by using a visible-light-sensitive photocatalyst obtained by doping Fe into TiO 2 for achieving high removal efficiency. According to the experimental results, photodegradation rate of the dye by 80% of 3%wt. Fe-doped TiO 2 with 20% v / v H 2 O 2 addition was achieved in acidic media with three successive recycling runs. Moreover, total organic carbon (TOC) values indicated that the dye was nearly mineralized into CO 2 and water. This result may be related to the terephthalate (TPA) analysis, indicating that the amount of generated hydroxyl radicals increases via H 2 O 2 addition. In addition, preliminary toxicological study was conducted focusing on contamination of Ti particles in selected plants after exposure to treated water. The antibacterial efficiency of the selected photocatalyst was further tested against Gram-positive and Gram-negative pathogenic bacterial strains. The results revealed that 3%wt. Fe-doped TiO 2 was highly efficient in inactivating Escherichia coli and Staphylococcus aureus after 3 h under visible light illumination. Overall, our results provided an alternative for an inexpensive, non-toxic, stable, efficient, reusable, and excellent catalytic performance of 3%wt. Fe-doped TiO 2 photocatalyst materials with significant tasks remained for future study, including dye contaminated wastewater treatment, bacterial growth inhibition and simultaneously solar harvesting.
:合成染料在各种工业中使用，对水质构成潜在威胁，对人类健康和环境产生不利影响。光催化是利用优良的半导体材料将光能光子转化为化学能，从而降解废水中有机污染物的一种有效技术。在此，我们强调了利用在tio2中掺杂Fe获得的可见光敏感光催化剂对废水进行处理以获得高去除效率的意义。根据实验结果，该染料的光降解率为80%，为3%wt。在酸性介质中，以20% v / v h2o2添加铁掺杂tio2，连续三次循环使用。此外，总有机碳(TOC)值表明染料几乎矿化成co2和水。这一结果可能与对苯二甲酸酯(TPA)分析有关，表明h2o2的加入增加了羟基自由基的生成量。此外，还开展了初步的毒理学研究，重点研究了选定植物接触处理过的水后钛颗粒的污染情况。进一步测试了所选光催化剂对革兰氏阳性和革兰氏阴性病原菌的抑菌效果。结果显示，3%wt。在可见光照射下，掺铁tio2对大肠杆菌和金黄色葡萄球菌的灭活时间为3 h。总的来说，我们的研究结果提供了一种廉价、无毒、稳定、高效、可重复使用和优异的3%wt催化性能的替代方案。铁掺杂tio2光催化剂材料在染料污染废水处理、细菌生长抑制和同步太阳能收集等方面仍有重要的研究任务。
