Photocatalytic multiphase micro-droplet reactors based on complex coacervation

Abstract

We describe the synthesis and characterisation of novel photocatalytic multiphase micro-droplet reactors comprising TiO₂ nanosheets dispersed in poly(diallyldimethylammonium) chloride and adenosine 5′-triphosphate or poly(ethylene glycol) 4-nonylphenyl 3-sulfopropyl complex coacervates. We demonstrate significant variations in the degree of equilibrium partitioning of small molecule dyes into the coacervate droplet systems and exploit this behaviour to successfully conduct selective photocatalytic dye degradation.
