“…There are several ways to improve the photocatalytic properties of PPy, for instance, compositing it with semiconductors, 9,19 conductive material (i.e., carbon nanotubes, CNTs), 20 or other excellent photodegradation materials. 21,22 The combination of PPy with CNTs was believed to be one the most effective route to enhance the photocatalysis activity, i.e., by means of decreasing the bandgap energy. At the same time, due to their excellent electronic properties, CNTs was also discovered as an effective additive for the degradation of dyes such as MB, 23 acetaminophen, 24 methyl orange (MO), 25 RhB, 26 reactive black 5, 27 dianix blue and vat green 1 dyes, 28 as well as sunset yellow and congo red.…”
