A 3–D Printed Millifluidic Reactor for Continuous Flow Photocatalysis in the Teaching Laboratory

An experiment designed to teach principles of continuous flow technologies for photocatalysis is 10 described as a part of a two-week summer camp program for high school students. Students learned about green chemistry, photocatalysis, flow chemistry, and the role of 3–D printing for the design and production of custom millifluidic reactors. Students examined reactor designs which differed in terms of residence times and mixing capabilities. Such evaluation was based on the combination of blue and yellow dyes, followed by running a photocatalytic thiol-ene reaction on gram-scale.
