Our research group is dedicated to pushing the boundaries of nanomaterial synthesis. The high-quality synthesis of materials serves as the foundation for exploring their properties and developing new functionalities, making it a fundamental driving force in physical science. Centered around the theme of “Nanocrystal Stereochemistry”, our research focuses on the methodology of chiral nanocrystal synthesis. We have established a systematic research framework that is grounded in nanocrystal growth theory, with Au-Ag-based nanomaterials as the core and sub-nanometer-scale phenomena and electrocatalysis as key orientations. By leveraging theoretical insights to guide precise synthesis and utilizing property exploration to refine synthesis strategies, we aim to systematically advance the methodology and utilization of chiral nanocrystal synthesis.
