Self-assembling TiO2 on aminated graphene based on adsorption and catalysis to treat organic dyes

Aminated graphene oxide (NGO) was synthesized by condensation of graphene oxide (GO) and diethylenetriamine (DETA). Highly catalytic nanostructured NGO-TiO2 composite catalysts were self-assembled by a two-phase system of toluene and water. The crystal structure, morphology, and optical properties of the composite catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet–visible spectrometry...
