One step to synthesis (rGO/Ni NPs) nanocomposite and using to adsorption dyes from aqueous solution

Nickel oxide nanoparticles (NiO NPs) were decorated on reduced graphene oxide via simples and easy reduction of graphene oxide and nickel salt in a single step reaction. By using some analytical techniques as well as, UV-vis spectrophotometry, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy and Fourier-transform infrared (FTIR) spectroscopy, has been characterized the nanocomposite (rGO/NiO NPs). The nanocomposite (rGO/NiO NPs) has been found more suitable to obtain complete removal around 4 min when used as dyes adsorption. The nanocomposite (rGO/NiO NPs) is better than other graphene-based adsorbents with respect to the performance. (C) 2019 The Authors. Published by Elsevier Ltd.
