目前的CO2催化转化研究通常采用单程实验室规模的反应器。为这些反应器优化的影响催化剂性能的操作条件不一定可用于大规模应用。 在此，我们报告了一种可扩展的光流体光反应器，该反应器基于涂有光催化剂的玻璃波导。在“管壳式”反应器设计中，管被内部光导波导所取代，这些波导具有特殊设计的散射表面，以使光辐射能够深入有效地穿透。 以逆水煤气变换（RWGS）为中试反应，考察了温度、光照和停留时间对该光反应器平台光催化活性的影响。
Current research in CO2 catalytical conversion is usually conducted with single-pass lab-scale reactors. Operating conditions affecting catalyst performance optimized for these reactors were not necessarily transferrable for large scale applications. Herein we report a scalable optofluidic photoreactor based on glass waveguides coated with photocatalyst. Inside the “shell-and-tube” reactor design, tubes are replaced by internal light-guiding waveguides with specially designed scattering surfaces to enable deep and efficient penetration of the light irradiation. Using reverse water–gas shift (RWGS) as a pilot reaction, the effect of temperature, light irradiation and residence time on the photocatalytic activity of this photoreactor platform was examined.
