| Abstract: The hydrothermal method was taken to preparing uniform C-sphere from glucose as the C source, then using ethylene glycol as the solvent, and nickel acetate, magnesium acetate and cerium chloride were added successively. Finally, the Ce-Mg-Ni/C nano-composite for hydrogen storage was producing. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to analyze the phase composition and morphology of the solvent-thermal synthesis the nano-composites. Hydrogen adsorption-desorption measurements were performed by an automatic controlled Sieverts. SEM analysis indicated that the pre-fabricated composites with atom radios of 2:1:2 and 23:4:7 presented a nano-scale structure in uniform C-sphere templates. The XRD analysis showed that Ce2MgNi2 and Ce23Mg4Ni7 have been formed as nano-composite with carbon, and the peaks of the second phase CeMg3 and CeNi3 were presented in XRD patterns. P-C-T (pressure-composition-temperature) test date revealed that the hydrogen adsorption capacity of Ce2MgNi2/C and Ce23Mg4Ni7/C composites reached 1.54% and 1.05%(w/w) at 50℃, respectively. |
