Hydrogenation properties of nanostructured Ti2Ni-based alloys and nanocomposites

摘要: Abstract Mechanical alloying and annealing at 1023 K for 0.5 h under an argon atmosphere were used to prepare Ti 2 Ni-based nanocrystalline alloys their nanocomposites. Ni alloy was chemically modified by Pd multi-walled carbon nanotubes. An objective of the present study is provide data on hydrogenation properties compounds containing and/or Alloys composites characterized X-ray diffraction, scanning electron microscopy equipped with energy dispersive spectrometer, transmission microscopy, atomic force evaluate phase composition, crystal structure, grain size, particle morphology distribution catalyst element. Hydrogenation/dehydrogenation hydriding kinetics materials measured using a Sievert's apparatus. Hydrogenation nanostructured nanocomposites compared those binary compound. In work we shown how mechanical method chemical modification MWCNTs affected hydrogen storage alloy. The highest capacity obtained Ni + Pd equaled 2.1 wt.%. Up our knowledge it so far materials.
