讲座内容：There has been an intensive search for heterogeneous single atom catalysts (SACs) of high activity, efficiency, durability and selectivity for a wide variety of electrocatalytic energy conversion and chemical reactions, in recent years. With the down-sizing from nanoparticles, clusters and now to single atoms, and the steady switching from noble metals to transition metals, there are steady changes in the bond and coordination environment for each and every atom involved. These single atoms are not “singles” anymore; they are actually “married” to the supporting surfaces, and their performance is largely controlled by the “marriage” with the substrate surfaces, instead of themselves. In this talk, I will present our latest advances in search for better heterogeneous single atom electrocatalysts, by focusing on their synthesis, control in composition, and strategies to realize the single atoms with the most desired bonds and coordination for targeted performance. Examples are those targeted for applications in the energy storage and conversion targeted for portable and flexible devices, and those for environments.
