In situ diagnostics and control of electrowetting of carbon nanotube catalysts for application in multiphase reactors (B02)

• Subject Area: Experimental Condensed Matter Physics ; Technical Chemistry
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 503850735

Electrowetting of Carbon Nanotube (CNT) Carpets carrying Ru-Cu and Ru-Fe nanoparticles will be developed as method for catalyst reactivity control inside a SMART multiphase reactor for catalytic glycerol hydrogenolysis. A miniaturized reactor module will be developed in another project, allowing simultaneous fibre-based Raman spectroscopy and hard X-Ray measurements at PETRAIII/DESY including SAXS, XAS, XRF and TXM. Goal is to establish a functional relationship between the shift of Raman bands of the CNT’s and the degree of electrowetting as measured by operando X-Ray spectroscopy. Fibre-based Raman spectroscopy can then be used for catalyst reactivity control in the SMART multiphase demonstration reactor for catalytic glycerol hydrogenolysis in the project.
