AbstractReplacement of precious metal catalysts by commercially available alternatives is of great importance among both fundamental and practical catalysis research. Nanostructured carbon-based and transition metal materials have demonstrated promising catalytic properties in a wide range of energy generation/storage applications. Specifically engineering carbon with guest metals/metal-free atoms can improve its catalytic activity for electrochemical oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), thus can be considered as potential substitutes for the expensive Pt/C or IrO2 catalysts in fuel cells, metal-air batteries and water splitting process. In this presentation, we will talk about the synthesis of nonprecious metal and metal free elements-doped carbon, and their application on electrocatalysis. The excellent ORR, OER and HER performance (high catalytic activity and efficiency) and reliable stability (much better than the commercial Pt/C or IrO2indicate that new materials are promising highly efficient electrocatalysts for clean energy conversion.

主讲人简介:



Dr. David Lou received his B.Eng. (1st class honors) (2002) and M.Eng. (2004) degrees from the National University of Singapore. He obtained his Ph.D. degree in chemical engineering from Cornell University in 2008. Right after graduation, he joined Nanyang Technological University (NTU) as an Assistant Professor. He was promoted to Associate Professor since September 2013, and to Full Professor since September 2015. He has published about 253 papers with a total citation of >37,000 (ISI) or >42,600 (Google scholar), and an h-index of 114 (ISI) and 121 (Google scholar) as of June 2017. His main research interest is on designed synthesis of nanostructured materials for energy and environmental applications. In particular, he has strong interest on synthesis of hollow nanostructures for different applications, such as lithium-ion batteries and supercapacitors. He also explores the applications of novel nanostructured materials for electrocatalysis and photocatalysis. He has received several important awards including the Young Scientist Award 2012 by National Academy of Science of Singapore. He also received the Nanyang Research Award 2012 by Nanyang Technological University. He was listed as a Highly Cited Researcher by Thomson Reuters in 2014 (in Materials Science), 2015 (in both Materials Science & Chemistry) and 2016 (in Materials Science, Chemistry & Environment). He is currently an Associate Editor for Science Advances.

Abstract: We use metal-organic frameworks (MOFs) as a unique platform to synthesize nanostructured functional materials with both controlled composition and structure. Due to the atomically arranged metal ions and organic ligands, as well as the wide variety of compositions and porous structures, MOFs can serve as unique precursors for easy preparation of metal-based materials, carbonaceous materials and nanocomposites with high porosity and tunable composition/structure.In this talk, I will briefly discuss some progress we have made in this area. Specifically, I will mention some examples of designed synthesis of nanostructured metal oxides, sulfides, nitrides, and carbides using MOF precursors. These MOF-derived nanomaterials exhibit interesting electrochemical properties.
