摘要

Nitrided TiO₂ nanotubes and PDMS microchannel were assembled in a photocatalytic device for organic dyes photo-degradation studies. By integrating a PDMS microchannel with the nitrided TiO₂ nanotubes array, a microfluidic photocatalytic device was obtained and characterized by morphological, chemical, and physical points of view. The fabrication process allows an easy integration of the obtained nitrided TiO₂ nanotubes with a microchannel into a microfluidic device for pollutant photodegradation. The high surface-to-volume ratio intrinsic in nanotubes structures has functional properties for harvesting light and is responsible for part of the interesting photocatalytic device performance. Another great advantage of nitrided TiO₂ nanotubes compared to just TiO₂ nanotubes, is the lower gap of 2.80eV achieved by plasma nitriding processes in PECVD reactor, which leads to an increase of 14% in the photocatalytic response to sun light.
