AB  - Titanium dioxide is the most suitable semiconductor for photocatalytic application due
to its high efficiency, increased stability, low-cost, and non-toxicity. However, it is
possible to enhance the photocatalytic activity of TiO2 by homogenizing it with
conductive polymers. One of the most attractive conductive polymers is polypyrrole
(PPy) owing to its stability, low-cost, and special redox properties. The aim of this work
was to obtain the TiO2/PPy nanocomposites with a higher photocatalytic activity
compared to TiO2. In order to determine the optimal content of PPy, four TiO2/x%PPy
samples (x = 0, 1, 3, and 5 wt.%) were synthesized and characterized by XRD and
TG/DSC analyses. The photocatalytic activity was examined towards the degradation of
toxic textile azo dye Reactive Orange 16. It was observed that an increase in PPy content
led to better adsorption capacity of the synthesized nanocomposites. Samples
TiO2/1%PPy and TiO2/5%PPy demonstrated better photocatalytic activity than TiO2,
while TiO2/3%PPy showed very similar photocatalytic activity to TiO2. Near complete
degradation of the dye (98 %) was reached in 75 min by using TiO2/1%PPy, comparing
to pure TiO2, which degraded the same amount of the dye in 120 min. Considering all
the obtained results, the optimal content of PPy in the composite for degradation of
Reactive Orange 16 is 1 wt.%.
