Abstract

The disastrous result of fast industrialization and uncontrolled industrial effluent discharge is the lack of fresh water. Scholars have endeavored to extract water from heavily contaminated industrial effluent by creating several materials capable of effective and environmental friendly treating of tainted water. In the subject of water treatment, three-dimensional (3D) printed complex architecture has shown to be an emerging technique. Recently, nanomaterials have reformed filter technology because of their improved morphological characteristics. The current study explores the uses of two-dimensional (2D) Manganese Telluride (MnTe₂) quantum dots (QDs) to decorate the 3D printed architecture for wastewater treatment. The photocatalytic performance of the QDs decorated 3D printed structures was demonstrated through the degradation of organic dyes (methylene blue (MB) and methyl orange (MO) dye) in both dark and light exposure conditions. The coated structures exhibited the ability to adsorb the organic pollutant and clean the contaminated water. We observe ∼78 % degradation efficiency for MB and ∼48 % for MO in dye concentrations of 10 mg/100 ml. A colorimetric detection method was used for real-time detection of degradation efficacy. The obtained results indicated that QDs decorated 3D printed system can be a significant system for wastewater treatment.

用于染料降解的碲化锰量子点装饰3D打印结构

快速工业化和不受控制的工业废水排放带来的灾难性后果是淡水资源的缺乏。学者们努力从严重污染的工业废水中提取水，创造了几种能够有效和环保地处理污染水的材料。在水处理领域，三维（3D）打印复杂结构已经成为一项新兴技术。近年来，纳米材料由于其形态特性的改善而改变了过滤技术。目前的研究探索了二维（2D）碲化锰（MnTe2）量子点（QDs）的用途，以装饰用于废水处理的3D打印建筑。通过在黑暗和光照条件下对有机染料（亚甲基蓝（MB）和甲基橙（MO）染料）的降解，证明了量子点修饰的3D打印结构的光催化性能。涂层结构具有吸附有机污染物和净化污染水体的能力。我们观察到，在10 mg/100 ml的染料浓度下，MB和MO的降解效率分别为~ 78%和~ 48%。采用比色检测方法实时检测降解效率。研究结果表明，量子点修饰的3D打印系统可以作为一种重要的废水处理系统。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
