The photochemical microreactor has been a burgeoning field with important application in promoting photocatalytic reactions. The integration of light-converting media and microflow chemistry renders new opportunity for efficient utilization of light and high conversion rate. However, the flexibility of emission light wavelength regulation and the universality of the microreactor remain significant problems to be solved. Here, a photochemical microreactor filled with fluorescent fluid is fabricated by a 3D printing technique. The light-converting medium in the fluorescent fluid is used to collect and convert light, and then delivers light energy to the embedded continuous-flow reaction channels to promote the chemical reaction process. With the merits of flowability, different light-converting media can be replaced, making it a general tool for photocatalytic reactions in rapid screening, parameters optimization, and kinetic mechanism research.
光化学微反应器一直是一个新兴领域,在促进光催化反应方面具有重要应用。光转换介质与微流化学的结合为光的高效利用和高转化率带来了新机遇。然而,发射光波长调节的灵活性和微反应器的通用性仍然是有待解决的重大问题。在此,通过3D打印技术制造了一种填充有荧光流体的光化学微反应器。荧光流体中的光转换介质用于收集和转换光,然后将光能传递到嵌入式连续流反应通道以促进化学反应过程。具有流动性的优点,可以更换不同的光转换介质,使其成为光催化反应快速筛选、参数优化和动力学机理研究的通用工具。
