UiO-66-NH2 has a good thermal stability (up to 773K), outstanding chemical stability with regard water, ethanol, benzene and N, N-Dimethylformamide. The GO-OOH is prepared from graphene oxide (GO) by carboxylation treatment, during which the hydroxyl and epoxide groups on the basal plane of GO are converted into carboxyl groups. To obtain more void space of an MOF and large surface area, synthesized GO–OOH/UiO-66-NH2 and GO/UiO-66-NH2. GO–OOH/UiO-66-NH2 composites were designed via coordination bond of the carboxyl groups of GO with zirconium ion of UiO-66-NH2.The morphology, structure and crystallinity of the composites were examined by Fourier-transform infrared spectroscopy(FT-IR), scanning electron microscope(SEM), transition electron microscopy(TEM) and X-ray diffraction(XRD). Electrochemical properties were characterized by cyclic voltammetry (CV) in 6M KOH electrolyte. |
