Galvanic replacement-mediated synthesis of hollow Cu 2 O–Au nanocomposites and Au nanocages for catalytic and SERS applications

Here we demonstrate the synthesis of hollow Cu 2 O–Au nanocomposites and Au nanocages via a galvanic replacement reaction (GRR) between Cu 2 O nanocubes and HAuCl 4 for catalytic and SERS applications.
