Controlled synthesis of materials can help deepen our understanding towards their structures, properties, structure-activity relationship and their application in various fields. Unlike crystalline materials, which possess periodic atomic arrangement, amorphous materials have short-range ordered atomic arrangement and long-range disordered atomic arrangement, so the controlled synthesis and study in the growth mechanism of amorphous materials have long been internationally recognized challenges, restricting the development of amorphous micro- and nanomaterials. In light of this, our research group focuses on developing synthesis methods of amorphous micro-nanomaterials with different dimensions, aiming to reveal the formation mechanism of amorphous micro-nanomaterials, and explore their catalytic, optical, mechanical properties and potential applications.
