Effect of the addition of graphite oxide on the morphology of boehmite crystals

Using graphene oxide (GO) as the additive, the boehmite (AlOOH) with various morphology including nanofibers, three-dimensional (3D)-microflowers and sea bile-like particles, can be easily synthesized by a two-stage hydrothermal method. The obtained products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). It was put forward that GO acted as a template during forming boehmite crystals, and its detailed effect has been discussed. (C) 2017 Elsevier B.V. All rights reserved.
