The Chen research group focuses on rational design and synthesis of functional nanomaterials for energy conversion and human-health related applications. We emphasize on rational design of materials for applications, precise synthesis of nanostructures, and in situ characterization of materials under reaction conditions or in actions. We aim to efficient and sustainable use of materials in applications, and fundamentally understand the synthesis-structure-property-performance relationship under operando conditions.
