嘉宾简介:
Shelley D. Minteer is the associated editor of Journal of the American Chemical Society, the USTAR Professor of Chemistry and Materials Science and Engineering in University of Utah, and members of American Chemical Society, AAAS, Society of electroanalytical Chemists, the Electrochemical Society, International Society of Eletrochemistry and Bioelectrochemical Society. Prof. Minteer received her BS degree in Chemistry from Western Illinois University and PhD degree in Analytical Chemistry with Johna Leddy from University of Iowa in USA. Then she started her research career in Saint Louis University as assistant professor, associated professor and finally full professor of Chemistry. In 2011 she moved to University of Utah and became the USTAR Professor of Chemistry and Material Science and Engineering. Prof. Minteer has published over 300 peer-reviewed scientific articles on Nature Chemistry, JACS, Angewandte Chemie, etc. Her publications have received more than 8000 citations. She has also 51 patents and edited 11 book chapters.
Prof. Minteer has received Saint Louis University Award for Excellence in Research (2003, 2006), Academy of Science of St. Louis Innovation Award (2005), Missouri Inventor of the Year Award (2006), U. S. Department of Defense Okaloosa Award (2006), Society of Electroanalytical Chemists Young Investigator Award (2008), Scientific American Top 50 Award (2008), Kavli Fellow of the National Academy of Science (2008), Tajima Prize of the International Society of Electrochemistry (2010-2011), Luigi Galvani Prize of the Bioelectrochemical Society (2015) and Celebrate U Top Researcher Honoree from the Utah College of Engineering (20017). Her research interest focuses on fundamentals and applications of (bio)electrocatalyts, particularly small molecular electrocatalysts and enzymes for biosensing, energy conversion and electrosynthesis.
报告摘要:
Recently there has been an increased interest in the development of small molecule electrooxidation catalysts such as (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO), for use in the anodic compartment of a biofuel cell. Some TEMPO derivatives are capable of electrochemically oxidizing short chain alcohols and various sugars to the corresponding aldehydes and carboxylic acids under physiological aqueous conditions. However, building libraries of such a catalyst is difficult due to the limited number of commercially available TEMPO derivatives and the lack of modular synthetic pathways to more complicated TEMPO structures. A promising alternative to the physical preparation of such libraries is the use of computational modeling to allow for in silico catalytic screening of a much wider range of TEMPO compounds. We have recently developed a descriptive model that correlates the electrocatalytic activity of nitroxyl radical catalysts to their redox potentials under aqueous conditions. Fundamental characteristics derived from this model have enabled the design of highly active and promiscuous catalytic materials. In addition, we have incorporated highly active TEMPO derivatives into an artificial protein to impart unusual selectivity onto the nitroxyl radical catalyst.
