Fe3O4/CuO/ZnO/Nano graphene platelets (Fe3O4/CuO/ZnO/NGP) composites prepared by sol-gel method with enhanced sonocatalytic activity for the removal of dye

One-pot microwave-assisted colloidal synthesis of Ag2O/ZnO/nanographene platelets composites: Photocatalytic studies

“…Cubic-Ag2O [6] and hexagonal wurtzite-ZnO [7] crystal phases are clearly noticed as marked by square (□) and hashtag (#) symbols, respectively, in the whole diffraction patterns. Yet, a typical peak from NGP (*) starts to occur with an additional NGP and more intense as its concentration increased [8]. Interestingly, crystal phase from silver (Ag) seems to be risen when the NGP was introduced into the Ag2O/ZnO composites as denoted by the circles (○) symbol.…”

“…In addition, the interlayer between p-and n-type of semiconductors will generate a p-n junction that will earn another benefit of enhancement of charge separation for photocatalytic application. Henceforth, the other ways to broaden the charge distribution of electrons and holes, outrageously conductive materials and possessing large surface area like nanograhene platelets are selected as a host material to optimize the organic pollutant photodegradation by oxide semiconductors [8].…”
