Abstract
In this work, Ni-doped graphene oxide/MIL-101 hybrid composites (Ni?GO/MIL) were prepared to investigate their hydrogen storage behaviors. Ni?GO/MIL was synthesized by adding Ni?GO in situ during the synthesis of MIL-101 using a hydrothermal process, which was conducted by conventional convection heating with Cr(III) ion as a metal center and telephthalic acid as organic ligands. The crystalline structures and morphologies were measured by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The specific surface area and micropore volume were investigated by N2/77 K adsorption isotherms using the Brunauer?Emmett?Teller (BET) method and Dubinin-Radushkevic (D-R) equation, respectively. The hydrogen storage capacity was investigated by BEL-HP at 77 K and 1 bar. The obtained results show that Ni?GO/MIL presents new directions for achieving novel hybrid materials with higher hydrogen storage capacity.
