英文摘要: The project focuses strategies to synthesize hollow porous carbon nanomaterials and yolk-shell carbon nanomaterials with controllable structures. With the aim to obtain promising hollow porous carbon nanomaterials and yolk-shell carbon nanomaterials for their potential applications, this project includes the following four parts: (1) New synthetic methods based on the cationic surfactant assisted resorcinol formaldehyde resin coating strategy will be developed to synthesize hollow porous carbon nanomaterials with the controllable structure parameters, such as methodologies, sizes, pore structures, and thickness and graphitic structures of hollow carbon shells. (2) Structure-activity relationship of hollow porous carbon nanomaterials will be investigated to design carbon nanomaterials with the specified structures for the targeted application fields, such as supercapacitor electrode, lithium batteries, and lithium-sulfur batteries. (3) Effective methods for synthesizing the yolk-shell carbon structures with controllable inner cores and hollow shell structures will be explored. (4) By designing the desired functional inner cores and optimizing the structure parameters of hollow porous carbon shells, the yolk-shell carbon nanomaterials with high performance will be created for lithium batteries and confined catalys
