Prof. Donghai Wang's Energy Nanostructure Laboratory (E-Nano) focuses on nanomaterial development for clean energy technologies, such as batteries, solar cells, fuel cells, and environmental remediation. The experimental research includes nanomaterial synthesis, characterization and device fabrication and evaluation. Nanomaterials are made by a variety of methods, including sol-gel method, high temperature synthesis, templating approach, and self-assembly. Material characterizations are performed using state of the art techniques. The nanomaterials are evaluated in fabricated devices such as batteries, solar cells, fuel cells and reactors for clean energy application. We aim to develop new materials to improve performance of the clean energy techniques and guide development of advanced energy techniques.
