Herein, a low-cost 3D printed photo-reactor system for the photo-chemical synthesis of silver nanoparticles with different morphologies is presented. Silver colloids with a variety of colors were obtained after light irradiation in continuous flow. The combination of milli-fluidic devices and LED light illumination clearly speeds up the growing process (hours) compared to batch systems (day to months) with similar initial colloids. Moreover, the effect of residence time, and reactant concentrations were investigated. Results indicated three stages, such as induction, growth, and termination during photo-aggregation within the continuous flow reactor. Moreover, H₂O₂ treated samples grew 3.5 times faster than non-treated AgNP colloids, with a complete NP formation under 4 h.

在此，提出了一种用于光化学合成具有不同形态的银纳米粒子的低成本 3D 打印光反应器系统。连续流光照射后得到各种颜色的银胶体。与具有类似初始胶体的批处理系统（每天到几个月）相比，毫流体设备和 LED 光照明的组合明显加快了生长过程（小时）。此外，研究了停留时间和反应物浓度的影响。结果表明连续流反应器内光聚集过程中的三个阶段，例如诱导、生长和终止。此外，H ₂ O ₂处理的样品比未处理的AgNP胶体的生长速度快3.5倍，在4小时内完全形成NP。
