Hollow-Core-Fibre Microreactors for Photocatalysis

We use optofluidic hollow-core fibres (HCFs), connected to microfluidic coupling cells, to monitor photocatalytic reactions in systems that combine molecular catalysts with particulate light absorbers. Our recent work focuses on molecular catalysts combined with carbon nanodots. Carbon nanodots (CNDs) are one of the most promising light-absorber materials due to their unique scalability, biocompatibility, water solubility, and stable optical properties. Key to improving their performance in solar catalysis are charge-transfer processes. This talk will review how these processes can be investigated through fibre-enhanced absorption-, fluorescence-, and Raman spectroscopy.
