Abstract
A type of novel material with a high hydrogen storage capacity was prepared by supporting PdNi18 alloy nanoparticles, which were synthesized by using a new colloid method, on the surface of pretreated multiwalled carbon nanotubes (MWCNTs). The average PdNi18 alloy particle sizes calculated from XRD patterns were ca. 3 nm, and the high dispersion of these particles on MWCNTs was confirmed by TEM image. Hydrogen storage performance of the composite was investigated under moderate pressure (0.1–1.5 MPa) at room temperature, and a maximum storage capacity of ca. 2.3 wt% was achieved under 1.5 MPa at room temperature, which was much higher than that reported previously under the same conditions.
