报告内容:

Multifunctional and hierarchical porous   materials have attracted much attention as host electrode materials for   electrochemical energy conversion and storages. Our research group has developed powerful methods to control multiscale porous inorganic   nanostructurs via simple “one-pot method” by employing blends of block   copolymers and homopolymers. The new approach allows access to a high degree   of control over pore structure and size, particle shape, particle size and   chemical composition including metal oxides, metal nitride and conductive   carbon. Multiscale porous materials have been employed as a multifunctional   sulfur host, integrating the advantages of multiscale porous architectures  with high performance electrocatalytic property to achieve high-power and  long-life lithium-sulfur batteries. A new and intuitive strategy for tuning and enhancing the kinetic activity of Fe-N4 sites was designed by controlling electro-withdrawing/donating properties of carbon plane. Fe-N4 integrated mesoporous   materials showed a high catalytic performance comparable to that of Pt/C in   anion exchange membrane (AEM) fuel cells.
