英文摘要: Abstract(#br)The present study focuses on the structure and pressure-composition (P–C) isotherm measurements of nanocrystalline Pr 5 Co 19 hydrides. The crystal structure and hydrogenation properties of Pr 5 Co 19 are investigated by X-ray diffraction, refined using Rietveld method, and by transmission electron microscopy (TEM). This intermetallic compound crystallizes in the rhombohedral (3R) with Ce 5 Co 19 -type structure.(#br)The pressure-composition isotherm of Pr 5 Co 19 was measured at room temperature. A single plateau was observed during the absorption-desorption process, the reversible hydrogen capacity reached 10 H/f.u (0.4 H/M). A peak broadening was observed in the X-ray diffraction (XRD) profile after hydrogenation, with no detection of any amorphous phase.(#br)The crystal...
