The efficacy of degradation of methylene blue dye and indigo carmine increased as initial concentration decreased. The optimum catalytic parameters such as initial organic dye concentration and pH were discussed. Sensitized zinc oxide with graphene oxide showed higher efficiency in the degradation of MB with a 96% of degradation efficiency after 70 min and 98% for IC after merely 27 min. The surface sensitization and morphology changes of the fabricated composite nanofibers were studied using Fourier transform infrared spectroscopy analysis, Scanning Electron Microscopy and transmission electron microscope. Composite nanofibers fabricated by using electrospinning technique followed by chemical cross-linking with zinc oxide. Photocatalytic degradation of two organic dyes methylene blue dye and indigo carmine dye from the simulated industrial wastewaters has been investigated under visible light irradiation. 220 EGP Add to cart Add to wishlist Sedki Sulayman Prime Minister of Egypt Newspaper. In this work, Polyacrylonitrile nanofibers were enhanced by graphene oxide and zinc oxide, in terms of enhanced the photocatalytic activity and mechanical properties for the composite nanofibers. For example, the editor of the Akhbar alYoum newspaper was jailed for half a year on false charges (Freedom House, 2011a).
