A mat based on PVA doped with TiO2 nanoparticles for removal of methylene blue dye from aqueous solution and improving the carbon footprint.

Water supply is the great challenge for climate change and overpopulation. A Nanofiber mat consisting of Poly vinyl alcohol (PVA), nanoTiO2, and citric acid (PTC) was prepared using an electrospinning technique at a constant flow rate (0.5 ml/h).
