Hollow PdCu Alloy Catalysts for Electroless Copper/nickel Deposition

We used a facile method to prepare PdCu hollow nanocubes (HNCs) and nanospheres (HNSs) for electroless copper or nickel deposition by via redox reaction with the sacrificial templates of Cu2O. The electrocatalytic performance of PdCu HNSs is higher than PdCu HNCs through CV and EQCM tests. Also, PdCu HNSs was applied to electroless copper and nickel deposition, and find that the quite low concentration up to 1 mM and 2 mM of PdCu alloy for electroless copper and nickel deposition still has the good catalytic performance, respectively. © 2017 IEEE.
