报告摘要:

The ability to create highly efficient, low-cost, and stable electrocatalysts, and to craft metalsingle atom catalysts (SACs) in which transition metal atoms are asymmetrically coordinatedwith organic heteroatoms, represents important endeavors toward accelerating sluggish water.oxidation kinetics and developing high-performance SACs over symmetrically coordinatedcounterparts, respectively. In this talk, I will discuss on unravelling photothermal and magneticfield effects of spinel nanoparticles to promote dynamic active sites generation, thereby markedlyenhancing their oxygen evolution reaction activity. Subsequently, I will present superiolbifimetional electrocatalysts for oxygen reduction reaction/oxygen evolution reaction, enabled byinterfacing single Fe atoms between wrinkled MoS2 and N-doped carbon nanospheres. Theyrender robust wearable zinc-air batteries with high capacity and outstanding cycling stabilityFinally, I will introduce confining asymmetrically coordinated Fe single atoms with nitrogen andphosphorus atoms within rationally designed, spoke-like, mesoporous carbon scaffolds to boosring-opening reaction of epoxides, leading to production of an array of pharmacologically.important B-amino alcohols.
