Controlling palladium nanowire size through electroless deposition process

An inexpensive electroless deposition technique has been used to build highly-ordered palladium nanowires on a porous stainless steel surface. The nanowire formation starts by aligning palladium nanoparticles in one direction, linking the nanoparticles so they become a nanowire bead by bead, ultimately forming a uniform wire. The diameter of the palladium nanowire can be controlled by the concentration of PdCl₂ in the plating bath. The experimental results reported here are promising for developing desired palladium nanowires in potential engineering applications.
