Abstract:
This paper reports high temperature liquid phase synthesis of Pd
nanowires using chemically modified porous anodic aluminium oxide as
template. In this synthesis process, oleic acid is used to modify the
inner wall of the pores and Pd$^{2 + }$ complex with oleylamine is
filled into the channel of the template. The complex is then reduced
to give oleylamine-capped Pd nanowires. This paper suggests that
oleic acid can improve the environment of inner wall of the pores,
leading to the formation of uniform Pd nanowires. The synthetic
process can be extended to make other types of nanowires.
