Featured with unique structural, electronic and chemical properties, nitrogen-doped graphene has shown attractive promise in the field of energy storage and conversion. As electrode materials in supercapacitors, N-doped graphene has demonstrated intriguing flexibility and superb performances in a wide electrochemical window, equipped with versatile properties as both cathodes and anodes for constructing high voltage devices.1 Graphene-doped graphene has also drawn extensive attention to metal-air batteries due to the good catalytic activity, large specific surface area and high electrical conductivity.2 Since pyridinic N brings electron-deficient characteristics to graphene, such N-doped graphene can serve as excellent substrates to distribute active material particles, and the composites can be used as electrode materials for Li ion batteries and Na ion batteries, as well as electrocatalysts for metal-air batteries. Finally, N-doped graphene presents a good platform for further heteroatom-doping, and endows N and S doped graphene as anode materials for Na ion batteries.3 In this talk, the success of N-doped graphene in the field of energy storage and conversion will be highlighted and the mechanism will be discussed from the combination of experiments and computations.

Dr. Zhen Zhou was born in Shandong, P. R. China in 1971. After he received his BSc (applied chemistry, in 1994) and Ph D (inorganic chemistry, with Prof. Yunshi Zhang, in 1999) at Nankai University, P. R. China, he joined the faculty at Nankai University as a lecturer in 1999. Two years later, he began to work in Nagoya University, Japan with Professor Masahiko Morinaga (Ex-President of the Japan Institute of Metals) as a postdoctoral fellow, under the support of the Japan Society for the Promotion of Science (JSPS), and then he continued his research at EcoTopia Institute, Nagoya University for another two years. In 2005, he returned to Nankai University as an associate professor of Materials Chemistry. In 2011, he was promoted as a full professor of Materials Science and Engineering at Nankai University. Now he is the director of Institute of New Energy Material Chemistry and Computational Centre for Molecular Science, Nankai University. So far, he has published over 200 scientific papers with ~10000 citations and personal h-index of 55, and 5 book chapters. His main research interest is the design, preparation and application of nanomaterials for energy storage and conversion.
