摘要：

In this work, we successfully prepare NiAl2O4/NiO nanocomposite with thermal decomposition method by using green tea extract (GTE) as precipitating agent. The biosynthesized NiAl2O4/NiO nanocomposite characterize using X-ray energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), N-2 adsorption (BET), ultraviolet visible (UV Vis) spectroscopy, and transmission electron microscopy (TEM). Also, we study the electrochemical hydrogen storage properties of NiAl2O4/NiO nanocomposite porous with different calcination temperature. The discharge capacity of samples with calcination temperature 700, 800 and 900 degrees C are 450, 325 and 800 mAh/g after 15 cycles, respectively. (C) 2016 Hydrogen Energy Publications LLC.
