The chemical industry is a major contributor to CO2 emissions as it accounts for about 30% of industrys' total energy use worldwide. Thus, disruptive technologies are needed to reduce its greenhouse gas emissions. Photochemistry in flow microreactors promises to sustainably produce chemical compounds and has received a lot of attention due to the prospect of utilizing (sun)light to drive these reactions. Still, the technique has not been widely used due to a challenging light management which hinders large-scale application in industry. This is exactly where reaCtor comes into play by offering an innovative solution: microreactors will be integrated inside a specialty optical glass fiber, where laser light is coupled in and the chemical reaction is en hancedby plasmonic nanoparticles, which locally amplify the optical field of the incoupled light. This approach allows to use a single light source for multiplereactors, thereby enabling a huge scale-up potential towards a sustainable chemical industry. Our goal is to set-up a demonstrator and benchmark it with photocatalytic reactions.
