报告内容简介：

Multifunctional and hierarchicalporous materials have attracted much attention as host electrode materials forelectrochemical energy conversion and storages. Our research group hasdeveloped powerful methods to control multiscale porous inorganic nanostructursvia simple “one-pot method” by employing blends of block copolymers andhomopolymers. The new approach allows access to a high degree of control overpore structure and size, particle shape, particle size and chemical compositionincluding metal oxides, metal nitride and conductive carbon. Multiscale porousmaterials have been employed as a multifunctional sulfur host, integrating theadvantages of multiscale porous architectures with high performanceelectrocatalytic property to achieve high-power and long-life lithium-sulfurbatteries. A new and intuitive strategy for tuning and enhancing the kineticactivity of Fe-N4 sites was designed by controllingelectro-withdrawing/donating properties of carbon plane. Fe-N4integrated mesoporous materials showed a high catalytic performance comparableto that of Pt/C in anion exchange membrane (AEM) fuel cells.
