Photocatalytic microreactors were simply prepared by mussel-inspired immobilization of TiO2 nanoparticles on poly(catechol)-enriched channel surface, showing high photocatalytic activity. The immobilized TiO2 nanoparticles from microreactor can easily regenerated by simple acid treatment. Taking this immobilize advantage, the liquid continuous-flow photocatalysis based immobilized TiO2 nanoparticles within the microreactor resulting prolonged operation scale up to 30 days. The mussel-inspired surface engineering of microreactors and immobilization of TiO2 photocatalysts was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier-transform infra-red spectroscopy (FT-IR) and X-ray diffraction (XRD). Regeneration of microreactors with diminished photocatalytic activity is also possible by simply acid treatment, enabling efficient cleaning of used microreactors for regeneration. |
