Miniaturization is a key aspect for many technological applications and the use of microreactors is an excellent solution for the intensification of chemical processes for a variety of applications. However, standard microfabrication requires large facilities and intricate fabrication protocols, and consequently it is not easily available, generally resulting in high production costs. Herein, we present a very cheap, fast, and easy microreactor design for photocatalytic applications based on direct fused filament three-dimensional printing as a facilitating and widespread technology. The microreactor consists of three bodies directly printed in ABS (acrylonitrile butadiene styrene): a main body with a serpentine microchannel pattern where the photocatalyst is placed, a top holder with a transparent polymer window, and a base to clamp the parts. Several microreactor units were coated with TiO2 doped with Cu (2.4 wt %) nanoparticles synthesized by flame spray pyrolysis and tested for the photocatalytic degradation of two water pollutants showing excellent performance.

用于光催化应用的丙烯腈丁二烯苯乙烯微反应器的三维印刷

微型化是许多技术应用的关键方面,而微反应器的使用是强化化学过程以适应各种应用的出色解决方案。但是,标准的微细加工需要大型设备和复杂的加工规程,因此不易获得,通常导致高生产成本。本文中,我们提出了一种基于直接熔丝三维印刷技术的光催化应用的非常便宜,快速和简便的微反应器设计,该技术是便利且广泛使用的技术。微型反应器由三个直接印制在ABS(丙烯腈丁二烯苯乙烯)中的主体组成:一个带有蛇形微通道图案的主体(用于放置光催化剂),一个带有透明聚合物窗口的顶部固定器以及一个用来夹持零件的底座。2掺杂有通过火焰喷雾热解法合成的Cu(2.4 wt%)纳米颗粒,并测试了两种水污染物的光催化降解性能,显示出优异的性能。
