Time:11:00 am – 12:00 pm


1) Porous metal-organic frameworks (MOFs) for energy applications We have developed new applications of porous MOFs, especially for energy conversion and storage.1 Novel porous metal-organic frameworks have been synthesized, which present stable catalytic activities for the oxidation of CO to CO2. Metal nanoparticles (NPs) have been immobilized to MOFs by the solid-grinding method, impregnation method and double-solvents approach in combination with the H2 reduction, liquid-phase concentration-controlled reduction and the CO-directed reduction at the solid-gas interface, which exhibit excellent catalytic performances for various reactions, including hydrogen generation from chemical hydrides. Porous carbons have been synthesized by using MOFs as templates/precursors and the resultant carbons display high specific surface areas and excellent electrochemical properties as electrode materials for electric double-layered capacitor (EDLC) and as catalysts for oxygen reduction reaction (ORR).

2) Metal nanoparticle-catalyzed hydrogen generation We have reported excellent liquid-phase hydrogen generation systems, which are based on metal nanoparticle-catalyzed hydrolysis of ammonia borane (NH3BH3), complete decomposition of hydrous hydrazine (H2NNH2) and decomposition of formic acid. The metal nanoparticles catalysts immobilized by the double-solvents method (DSM) inside the pores of MOFs, by the non-noble metal sacrificial approach (NNMSA) to reduced graphene oxide and by the weakly-capping growth approach (WCGA) to carbon nanospheres will be discussed. The use of soluble porous organic cages as a stabilizer and homogenizer toward the homogenization of heterogeneous metal nanoparticle catalysts with enhanced catalytic performance will also be discussed.

Prof Qiang Xu received his PhD degree in Physical Chemistry in 1994 at Osaka University, Japan. After one year working as a postdoctoral fellow at Osaka University, he started his career as a Research Scientist in Osaka National Research Institute in 1995. Currently, he is a Chief Senior Researcher at National Institute of Advanced Industrial Science and Technology (AIST, Japan), adjunct professor at Kobe University and fellow of Royal Society of Chemistry (FRSC). He received the Thomson Reuters Research Front Award in 2012 and was recognized as among the highly cited researchers (2014 & 2015) in both fields of Chemistry and Engineering for publications in 2002–2012 & 2003–2013 by Thomson Reuters. His research interests include syntheses of nanostructured materials, in particular porous materials, and related functional applications, especially for clean energy. He has published more than 300 papers in refereed journals with more than 13000 citations and h-index > 62.
