Abstract

Abstract In this work, an efficient and green approach has been presented to prepare carbon quantum dots (CQDs) from watermelon juice through a microfluidic steam-based method, with a view to enabling continuous production at scale, i.e., to save time, costs, or energy as compared to conventional production using an autoclave. The evolution of the product formation through multifarious intermediates generated in different stages of the reaction process was characterized. Computational fluid dynamics simulations reveal the pressure and velocity profiles in the microchannel to exert process control. These determine the quality of the obtained CQDs by influencing the particle size transformations and manifold chemicals along the microchannel axis. The optimal reaction conditions and reaction mechanism for the synthesis of CQDs were investigated. Additionally, the synthesized CQDs demonstrated good fluorescence properties as well as a specific response to NO 2 − {\text{NO}}_{2}^{-} in both fluorescence and spectrophotometric modes, providing great potential for their application in environmental monitoring.

基于微流体蒸汽合成发光碳量子点作为检测亚硝酸盐的传感探针
摘要在这项工作中,提出了一种高效、绿色的方法,通过基于微流体蒸汽的方法从西瓜汁中制备碳量子点(CQD),以实现大规模的连续生产,即与使用高压釜的传统生产相比,节省时间、成本或能源。表征了在反应过程的不同阶段产生的各种中间体对产物形成的演变。计算流体动力学模拟揭示了微通道中施加过程控制的压力和速度分布。这些通过影响沿微通道轴的颗粒尺寸转变和多种化学物质来确定所获得的CQD的质量。研究了合成CQDs的最佳反应条件和反应机理。此外,合成的CQD在荧光和分光光度模式下都表现出良好的荧光性质以及对NO2−{\text{NO}}_{2}^{-}的特异性响应,为其在环境监测中的应用提供了巨大的潜力。

期刊介绍: Green Processing and Synthesis is a bimonthly, peer-reviewed journal that provides up-to-date research both on fundamental as well as applied aspects of innovative green process development and chemical synthesis, giving an appropriate share to industrial views. The contributions are cutting edge, high-impact, authoritative, and provide both pros and cons of potential technologies. Green Processing and Synthesis provides a platform for scientists and engineers, especially chemists and chemical engineers, but is also open for interdisciplinary research from other areas such as physics, materials science, or catalysis.
