摘要：
The design and synthesis of new hydrogen storage nanomaterials with high capacity at low cost is extremely desirable but remains challenging for today's development of a hydrogen economy. As a new type hydrogen storage material, Co(OH)(2)/rGO nanocomposites were successfully obtained through a facile method in this study. Through the measurements of X-ray diffraction, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), cyclic voltammetry and galvanostatic charge/discharge, it indicated that Co (OH)(2)/rGO nanocomposites showed a veil-like microstructure, consisting of interlaced nanorods with a diameter of 4-8 nm on rGO nanosheets. The hydrogen storage capacity was up to 400 mAh/g at room temperature, higher than those of graphene and Co(OH)(2).
