Abstract:

Abstract In this study, chemical de-alloying method was used to prepare nanoporous gold (NPG) from the Au containing amorphous alloy, with chemical composition of Au 20 Cu 48 Ag 7 Pd 5 Si 20 . Gold nanostructures were electrodeposited on the nanoporous gold by adjusting the applied potentials and deposition times. Using Rhodamine 6G (R6...More
