Investigation of TiO/PPy nanocomposite for photocatalytic applications; synthesis, characterization, and combination with various substrates: a review.

The use of photocatalysis technology, specifically visible light photocatalysis that relies on sustainable solar energy, is the most promising for the degradation of contaminants. The interaction of conducting polymer and titanium dioxide (TiO) leads to the exchange that enhances the alteration of the semiconductor's surface and subsequently decreases the bandgap energy. Polypyrrole (PPy) and TiO nanocomposites have promising potential for photocatalytic degradation.
