Proceedings Paper

A scalable glass waveguide-based optofluidic photoreactor for converting CO2 to fuels (Conference Presentation)

Paper Abstract

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.
