Enhanced photocatalytic activity of electrospun TiO2/polyacrylonitrile membranes in a crossflow reactor using dual lights

Abstract Photocatalytic membranes reactors have become one of the most efficient technologies to treat polluted waters. However, a major drawback is unilateral irradiation membrane, where only side membrane exploited. To overcome this issue, we developed reactor can be irradiated on both sides. Polyacrylonitrile containing different amounts TiO 2 nanoparticles up 60% were first prepared by electrospinning. These used in 3D-printed crossflow photocatalytic for degradation methylene blue under combinations lights. The use sides significantly enhanced activity decolorization water. showed best rate loading and dual ultraviolet lights, solution was completely discolored after 90 min. This report such system configuration, new concept promising reactions water cleaning.
