Synthesis and Kinetic of Palladium Nanotube using Polymer Compound

摘要

The palladium nanotube was synthesized by template wetting and annealing process. And the activation energy for formation of the palladium metal from palladium acetate was evaluated. The activation energy was evaluated by Friedman method and the values were in the ranges between 65 and 98 kJ/mol. The diameters and lengths of synthesized palladium nanotubes ranged from 130 to 190 nm and from 2 to 3 μm, respectively. The palladium nanotubes can be successfully fabricated by the template wetting process, and the crystalline structure is confirmed by XRD. From DSC results the thermal decomposition of precursor containing palladium acetate/PLLA occurred at 248℃, which corresponds to the precipitation of palladium metal.
