CRC 1615 - Project B02: In situ diagnostics and control of electrowetting of carbon nanotube catalysts for application in multiphase reactors

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 project B02, 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 project C03.
