摘要：

This paper describes the fabrication and electrochemical behavior of hierarchical nanoporous gold film (HNPGF) electrode by multi-cyclic electrochemical co-alloying/dealloying of two sacrifice metals (Zn and Sn) with gold. Different from the nanoporous gold film (NPGF) formed in the electrolyte of ZnCl2 in benzyl alcohol, the HNPGF obtained possessed special hierarchical porous structure and extra high roughness factor of 1250. This study reveals that hierarchical porous gold film electrodes are promising for catalysis. (C) 2009 Elsevier B.V. All rights reserved.
