报告摘要:

During the past 20 years, a number of supramolecular or nanoscopic structures have been assembled from molecules, nanoaprticles and nanocrystals. However, the future of nanoscience is not to only make structures, but more importantly to endow structures with functions. In this context, we can not only control/direct self-assembly from supramolecular to nanoscopic level by using various intermolecular interactions, but also make these nanostructures functional. Specifically, we explored the applications of these structures in the following four areas: (1) photoswitchable nanoparticulate catalysis system in which the catalysis can be switched “ON” or “OFF” by using visible or UV light; (2) a core/shell catalytic reactor that can direct tandem reaction selectively going the desired sequence and avoiding the formation of byproducts; (3) enhanced photocatalytic activity of hybrid Fe2O3-Pd nanoparticulate catalysts where Pd nanodomain was used as cocatalysts to improve photoexcited charge separation and suppress the probability of the electron-hole recombination; (4) photocatalytic metal-organic frameworks (MOFs) which can effectively photoreduce various metal salts to their corresponding nanoparticles and is potentially photocatalysts for visible light driven organic synthesis, CO2 reduction and water splitting.
