Abstract

Heterojunction composites of both graphene oxide (GO) and reduced graphene oxide (rGO) were successfully fabricated onto the in-situ growth of the metal organic framework, ZIF-8, by utilizing solution-based techniques. The crystal phases, functionalization, and adsorption capabilities were characterized using x-ray diffraction, Fourier-transform infrared, and ultraviolet-visible spectroscopy respectively. ZIF-8 crystal phases were dominant in the composite with the GO and rGO amorphous phases completely sorbed into the structure. Key functional groups were identified such as hydroxyl, aromatic, and aromatic amines and were used to differentiate the composites to the precursors. The reduction and the use of ZIF-8 were instrumental to improve the absorption characteristics of the resulting composite.
