High-Density Nanoporous Structures for Enhanced Electrocatalysis

A novel method to create a high-density nanopore structure between the neighboring pores of anodic alumina template is developed via applying a simple consecutive three-step anodization process. As a demonstration, the nanostructure comprising more numbers of individually addressable Pd nanorods was utilized to enhance the electrocatalysis of ethanol in alkaline media, which is due to a dramatic increment in surface reactive sites.
