主讲人/SpeakerLiming Dai, Ph.D., Kent Hale Smith Professor, Department of Macromolecular Science and Engineering, Director of Center of Advanced Science and Engineering for Carbon, University of Case Western Reserve University, USA


Prof. Dai received a BSc degree from Zhejiang University in 1983, and a PhD from the Australian National University in 1991. He joined Case Western Reserve University (CWRU) in fall 2009 as the Kent Hale Smith Professor in the Department of Macromolecular Science and Engineering. He spent 10 years with the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Melbourne, Australia. Dr. Dai’s expertise covers the synthesis, functionalization, and device fabrication of conjugated polymers and carbon nanomaterials for energy-related and biomedical applications. He has published more than 500 scientific papers with citations over 70,000 and an h-index of ~140 (Google Scholar), and held about 30 issued/applied patents. He has received various awards, most recently receiving the 2018 NASA-Langley Henry J.E. Reid Award, 2019 IUMRS-Somiya Award from the International Union of Materials Research Societies, and 2019 Australian Laureate Fellowship.


报告题目/Title:

Ten Years of Metal-free Carbon Electrocatalysts


讲座摘要/Abstract:

Catalysis is a major field in science and engineering. Among the numerous catalytic reactions, the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) are critical for clean and renewable energy technologies. In 2009, They demonstrated that nitrogen-doped carbon nanotubes (N-CNTs) could be used as heteroatom-doped metal-free carbon electrocatalysts to replace Pt for the ORR in fuel cells. The improved catalytic performance was attributed to the doping-induced charge transfer from carbon atoms adjacent to the nitrogen atoms to change the chemisorption mode of O2 and to readily attract electrons from the anode for facilitating the ORR. Great progress has been made since the first metal-free carbon electrocatalyst was discovered over 10 years ago. In this talk, He will summarize some of their work on the development of metal-free carbon electrocatalysts for various energy-related reactions, along with an overview on the recent advances and perspectives in this exciting field.
