nanoparticles and graphene oxide flakes are incorporated as fillers into Nafion membranes and the photocatalytic properties of such nanocomposites are investigated. The study has been performed by measuring the degradation of methylene blue (MB) and methyl orange (MO) under UV/visible light illumination by absorbance measurements. We show the use of photocatalytic nanomaterials incorporated into membranes is advantageous for the removal and/or degradation of contaminants from water, since it gets rid of nanoparticle dispersion in water and allows the reuse of the photocatalysts.
