| 摘要: |
Synthesis of the intermetallic compound ZnPd by
(i) coreduction of Pd2+ and Zn2+ by Superhydride, (ii) the use of
ZnH2 as a reducing agent and simultaneously as a Zn source, as
well as (iii) electroless plating of nanoparticulate Zn with Pd2+ is
systematically explored. Chemical and differential thermal
(DTA/TG) analysis, as well as infrared spectroscopy, confirmed
the formation of ZnH2 as isolable intermediate during the
reduction of Zn2+ with Superhydride. Powder X-ray diffraction
(XRD), transmission electron microscopy (TEM), and fractional
sedimentation by disk centrifugation were applied to characterize
the nanoparticulate products concerning their phase composition,
crystallinity, and particle size distribution, respectively.
While all routes lead to nanoparticles of ZnPd, electroless plating
additionally allows one to control the crystallite size of ZnPd in a
range of 2？5 nm. |
