Anion Exchange Impedes Subsequent Cation Exchange: Ion Mobility Is Altered by Vacancies and Ion Size.

ABSTRACT: One method of achieving spatially specific, multi-component nanoheterostructures is to combine multiple forms of post-synthetic modification. Applying cation or anion exchange to Cu_2-xS nanorods creates complex nanoheterostructures. Combining such anion and cation exchanges generates a system which uncovers the interplay between these two processes and understands the cooperativity between postsynthetic modifications more broadly. Cd²⁺ exchange was carried out on various plasmonic and nonplasmonic Cu_2-xS/Cu_2-xTe nanoheterostructures to test how the presence of Te^2- ions would affect the extent of Cd²⁺ incorporation. Three hypotheses were presented for how the presence of Cu_2-xTe could a
