... by scanning electron microscopy (SEM), Raman and Fourier-transform infrared spectroscopy (FT/IR). Samples were stained with methylene blue (MB) and then exposed to solar light for different periods. Color changes of the samples were examined with a spectrophotometer. Air permeability, abrasion and tear...

... and exceptional dye degradation efficiency was observed. Within 25 min, 99 per cent of methylene blue was removed from waste water. Originality/value A novel one-pot synthesis of the composite was introduced. Transmission electron microscopy (TEM) and selected area electron diffraction were conducted using...
