Area of Science:

  • Materials Science
  • Chemical Engineering
  • Environmental Science

Background:

  • Photocatalytic degradation is a promising method for removing organic pollutants from water.
  • Titanium dioxide (TiO2) is a widely used photocatalyst, but its efficiency is limited under visible light.
  • Gold nanoparticles (AuNPs) can enhance photocatalytic activity through plasmonic effects.

Purpose of the Study:

  • To develop a microfluidic reactor for efficient photocatalytic degradation of organic pollutants using AuNPs and TiO2 under visible light.
  • To investigate the role of AuNPs in enhancing the photocatalytic activity of TiO2.
  • To evaluate the stability and reusability of the developed microreactor.

Main Methods:

  • Fabrication of a TiO2 film decorated with AuNPs on a fluorine-doped tin oxide (FTO) substrate within a microfluidic reactor.
  • Characterization of the TiO2/AuNP film's optical absorption properties.
  • Testing the photocatalytic degradation of methylene blue under visible light.
  • Assessing the stability of the microreactor over multiple reaction cycles.

Main Results:

  • The TiO2/AuNP film exhibited strong absorption in the 400-800 nm range.
  • The microreactor enhanced the reaction rate constant for methylene blue degradation by 13 times compared to bare TiO2.
  • The TiO2/AuNP microreactor demonstrated negligible loss of photoactivity after five cycles, indicating good stability.

Conclusions:

  • The developed plasmonic photocatalytic microreactor effectively utilizes AuNPs and TiO2 for efficient visible-light degradation of organic pollutants.
  • The TiO2 layer effectively protects AuNPs from detachment and photocorrosion, ensuring reactor stability.
  • The simple, low-cost fabrication and high performance suggest potential applications in continuous water treatment and artificial photosynthesis.
