When the electrodes are processed as polycrystalline films to meet the cost constraint for commercial viability, particle shapes, sizes, orientations, and interconnections significantly affect the chemical and physical factors that define the energetics and kinetics of these electrode materials. Therefore, rationally controlling micro- and nano-scale structures of electrode materials that compose polycrystalline films, and understanding the effects that micro- and nano-structures have on functional properties are the keys to producing highly efficient and cost effective electrode materials. To address these issues, we have been developing various new electrochemical synthetic strategies to produce electrode and catalyst materials with systematically and precisely regulated compositions and architectures (Figure 1). In this presentation, we will discuss in detail the design, control, and optimization of various electrodes and their applications for clean energy production (e.g. solar energy conversion).For more information contact Prof. John Zhang (404-894-6368).Related Links Prof. Kyoung-Shin Choi, Purdue University
