Abstract

Ag microcubes with a hierarchical porous structure were successfully prepared by a galvanic replacement reaction (GRR) on Cu foil through a subsequently facile two-step process. Firstly, and most importantly, Cu₂O nano cubes which serves as sacrificial template were synthesized by anodic oxidation of Cu using the dilute hydrochloric acid as an electrolyte for the first time. Compared with traditional thermal synthesis method for the Cu₂O cubes, the electrochemical method is direct, convenient and cost-effective. Then, the cubic Cu₂O covered Cu substrate reacts with AgNO₃ and forms porous Ag micro-cubes. The porous Ag with three-dimensional structure is a promising material in Raman Sensor.
