Size and aspect ratio control of Pd₂Sn nanorods and their water denitration properties

Abstract

Monodisperse Pd₂Sn nanorods with tuned size and aspect ratio were prepared by co-reduction of metal salts in the presence of trioctylphosphine, amine, and chloride ions. Asymmetric Pd₂Sn nanostructures were achieved by the selective desorption of a surfactant mediated by chlorine ions. A preliminary evaluation of the geometry influence on catalytic properties evidenced Pd₂Sn nanorods to have improved catalytic performance. In view of these results, Pd₂Sn nanorods were also evaluated for water denitration.
