Nanomaterials represent a possible solution to solve many of the current issues involving water quality, but several limitations exist for efficient applications, primarily concerning the dispersion of such nanomaterials in water, their recovery after water treatment and the resulting impact on human health and ecosystems. We present an approach based on the incorporation of several nanomaterials into polymeric composites as a valid solution to overcome these problems. We embedded active TiO2 nanostructures in poly (methyl methacrylate) (PMMA), with the advantage of no need of recovery of the nanoparticles after water treatment. Furthermore, we combined titanium dioxide nanoparticles with single walled carbon nanotubes, as acceptor of electrons, and obtained a significantly higher photocatalytic efficiency under UV irradiation, compared to the systems with TiO2 only. Photoactive materials even under visible …
