A branched material based on biomimetic design: Synthesis and electrochemical properties
Based on the biomimetic route the metal material with tree-like fractal structure was prepared, which showed a rough surface observed by scanning electron microscopy. According to the electrochemical experiments, the formed material exhibited the strong catalytic capability as an electrode in hydrogen evolution reaction, comparing with other conventional structure materials under comparable scales. We suggested this promotion of property arose from the contribution of the great surface area and the excellent connectivity offered from the fractal structure. (c) 2005 Elsevier B.V.
