Speech Title : Rationally designed nanomaterials for high-performance energy storage

Professor Jun Song CHEN received his Ph.D. at Nanyang Technological University in 2012. After that, he worked at the Max Plank Institute of Colloids and Interfaces as an Alexander von Humboldt researcher from 2013 to 2014. He is now a Professor at the School of Materials and Energy, University of Electronic Science and Technology of China. He was one of the “Thomson Reuters Highly Cited Researchers” in 2015 and 2016, and “Elsevier Chinese Highly Cited Researchers” in 2017. His research interests include the design of nanostructured materials for energy-related applications, such as supercapacitors, lithium-ion batteries, and water splitting.

Abstract: Design of new materials has been an important focus for the development of next generation energy storage devices. In this talk, different materials with unique nanostructures for energy storage, such as lithium-ion batteries (LIB), or supercapacitors, will be discussed. First, anatase TiO2 nanosheets with exposed (001) high-energy facets for high-power LIBs will be introduced, followed by self-supported nickel-based nanoarrays for supercapacitors with high energy density. By setting these two types of materials as examples, the importance of rational design of nanomaterials to improve their electrochemical properties is emphasized.

Speech Title : Fabrication of the Functionalized Carbon Nanomaterials via Catalytic Pyrolysis of Heteroatom-Containing Compounds

In 1997 I was graduated from Omsk State University. From 1999 to 2001 I was post-graduate student at Boreskov Institute of Catalysis of Siberian Branch of Russian Academy of Sciences, Russia. I defended my PhD thesis entitled “Catalytic dehydrogenation of methanol over supported copper catalysts” in 2005. From 2004 till 2014 I was an associate professor at Novosibirsk State Technical University, Russia. At the same time, since 2004 till 2008 I was a scientific researcher at Boreskov Institute of Catalysis. In 2008 I became a scientific secretary of the institute. Now I am a deputy director on science of BIC, head of Laboratory for nanostructured catalysts and sorbents research, head of Department of materials science and functional materials. My scientific interests are heterogeneous catalysis, oxide and metal catalysts, carbon nanostructures, carbon-based composites, dense and porous membranes, nanomaterials, nanotoxicology, etc.

Abstract: Commercial Ni-Cr and specially prepared Ni-Pd alloys were used as a catalyst’s precursor for the synthesis of the heteroatom-doped carbon nanofibers. In order to provide the intercalation of the doping heteroatom into the structure of the carbon product, the synthesis was performed in the one pot regime, when heteroatom-containing substance was subjected to decomposition simultaneously with carbon source compound. Chlorobenzene, 1-bromobutane, 1-iodobutane, and melamine were used as heteroatom- and carbon-containing sources in the experiments carried out in a closed reactor system. 1,2-dichloriethane, being a source of chlorine and carbon, was decomposed in a flow-through reactor system. Additionally, acetonitrile and carbon dioxide were admixed to 1,2-dichloriethane as nitrogen and oxygen sources. It was found that in all the cases, except for halogenated butanes, the amount of the intercalated heteroatom can reach 3-8 at.%. Both the substrate’s nature and the composition of the reaction mixture were found to affect the morphologic features of the carbon nanostructures produced.
