Nanomaterials Design for Energy and Environment

Nanotechnology has provided a novel technology platform which can address critical energy and environmental problems and enable new opportunities. In the past decade, my group has conducted research on new ideas to address problems related to energy conversion, storage and saving, and environment cleaning (air, water and soil). Here I will show exciting examples, including: 1) high energy battery materials including Si and Li metal anodes and S cathodes; 2) electrochemical tuning of catalysts; 3) Water disinfection using conducting nanofilters and uranium extraction for seawater. 4) Nanofiber air filters for efficient PM2.5 removal and low air resistance. 5) Cooling and heating textile for personal thermal management. Nanotechnology represents the most important foundational technology platform to impact nearly all areas of applications.
