Advanced and eco-friendly construction materials are being developed to reduce pollution and improve wastewater treatment efficiency. One such material is a photocatalytic nanocomposite that uses industrial wastes and natural substances to eliminate pollution. A recent study explored using an inorganic polymer composite (FM) made from a mixture of 70% fly ash and 30% metakaolin, with sodium hydroxide and sodium silicate as an alkali activator. The study evaluated the mechanical and hydration characteristics of the FM composite after 28 days in 100% humidity at room temperature. The study also examined the effect of adding 2.5 wt.% of Nano-TiO to FM composite and how it affects its properties. Results indicate that adding Nano-TiO to FM composite enhances its mechanical, antibacterial, and photocatalytic capabilities. Specifically, FM-TiO composite showed 90% removal of reactive blue 19 dye effluent in sunlight after 90 min, making it an excellent choice for sustainable wastewater treatment. This study presents a cost-effective, eco-friendly solution to wastewater treatment, with added antimicrobial properties from Nano-TiO.
人们正在研发先进且环保的建筑材料，以减少污染并提高废水处理效率。其中一种材料是光催化纳米复合材料，它利用工业废料和天然物质来消除污染。最近的一项研究探索了使用由70%粉煤灰和30%偏高岭土的混合物制成的无机聚合物复合材料（FM），并以氢氧化钠和硅酸钠作为碱激发剂。该研究评估了FM复合材料在室温下100%湿度环境中放置28天后的力学和水化特性。该研究还考察了向FM复合材料中添加2.5 wt.%的纳米二氧化钛的效果及其对复合材料性能的影响。结果表明，向FM复合材料中添加纳米二氧化钛可增强其力学、抗菌和光催化能力。具体而言，FM-TiO复合材料在阳光下90分钟后对活性蓝19染料废水的去除率达90%，使其成为可持续废水处理的理想选择。本研究提出了一种经济高效、环保的废水处理解决方案，纳米二氧化钛还赋予了其抗菌性能。
