Microfluidics-enabled catalysis applications of ZnO materials. (A) Microfluidic device with integrated ZnO nanowires for photodegradation of MB. Reproduced with permissions from reference60, copyright 2013, Elsevier. (B) Schematic illustration of the experimental setup used for water decontamination. The microfluidic reaction chamber including ZnO nanowires acting as photocatalyst is exposed to ultraviolet (UV) light while water is flowing, leading to purified water at the outlet.
