| الوصف: | A job-sharing hydrogen storage mechanism is proposed and experimentally investigated in Ru/Li2O nanocomposites in which H+ is accommodated on the Li2O side, while H- or e(-) is stored on the side of Ru. Thermal desorption-mass spectroscopy results show that after loading with D-2, Ru/Li2O exhibits an extra desorption peak, which is in contrast to Ru nanoparticles or ball-milled Li2O alone, indicating a synergistic hydrogen storage effect due to the presence of both phases. By varying the ratio of the two phases, it is shown that the effect increases monotonically with the area of the heterojunctions, indicating interface related hydrogen storage. X-ray diffraction, Fourier transform infrared spectroscopy, and nuclear magnetic resonance results show that a weak (LiOD)-D-. bond is formed after loading in Ru/Li2O nanocomposites with D-2. The storage-pressure curve seems to favor H+/H- over H+/e(-) mechanism. |
