| Abstract Scope |
This talk will focus on hierarchical hybrid nanostructures (HHN) designed to maximize the surface area, solid-fluid interactions, and charge transfer in portable and efficient electrodes for electrical and electrochemical systems. The HHN comprise of high-porosity substrates enriched with covalently bonded carpet-like arrays of highly conducting carbon nanotubes (CNT), which can be further functionalized with application-specific catalysts and/or chemical receptors. This architecture has shown unprecedented advantages in a wide variety of applications such as thermal exchange, radiation shielding, pollutant degradation, and tissue engineering. This presentation will focus on the electrochemical properties of HHN electrodes specifically tailored energy conversion and chemical detection. It is seen that this electrode architecture can significantly improve the performance of water electrolyzers, and also the detection capability of challenging industrial pollutants. Structure property relationship of these materials will be presented along with their potential impact on future technologies related to energy and environment. |
