One-pot synthesis and enhanced catalytic performance of Pd and Pt nanocages via galvanic replacement reactions

Abstract

A one-pot approach for the synthesis of Pd and Pt nanocages has been demonstrated via galvanic replacement reactions, in which the nanocage sizes and shapes can be effectively controlled through modifying the sizes of Ag nanocubes and reaction temperatures. Moreover, the Pd and Pt nanocages have excellently monodispersed feature in aqueous solution, and show outstanding electrocatalytic activities without introducing any loading materials.
