Microfluidic reactors for visible-light photocatalytic water purification assisted with thermolysis.

摘要: Photocatalytic water purification using visible light is under intense research in the hope to use sunlight efficiently, but conventional bulk reactors are slow and complicated. This paper presents an integrated microfluidic planar reactor for visible-light photocatalysis with merits of fine flow control, short reaction time, small sample volume, long photocatalyst durability. One additional feature that it enables one both heat energy source simultaneously. The consists a BiVO4-coated glass as substrate, blank slide cover, UV-curable adhesive layer spacer sealant. A blue emitting diode panel (footprint 10 mm × 10 mm) mounted on microreactor provide uniform irradiation over whole chamber, ensuring optimal utilization photons easy adjustments intensity temperature. may versatile platform studying combined conditions such different temperatures, intensities, rates. Moreover, demonstrates significant photodegradation time about 10 s, much shorter than typically few hours reactors, showing its potential rapid kit characterization performance.
