Abstract: Since our discovery of the first carbon-based metal-free electrocatalyst (C-MFEC, i.e., N-doped carbon nanotubes) for oxygen reduction in fuel cells in 2009, the field of C-MFEC has grown enormously. C-MFECs, as alternatives to noble metal-based electrocatalysts, have been widely demonstrated for efficient oxygen reduction, oxygen evolution, hydrogen evolution, carbon dioxide reduction, nitrogen reduction, and many other electrocatalytic reactions. Recent worldwide research effort has shown great potential for applications of C-MFECs in fuel cells for clean energy conversion, metal-air batteries for energy storage, water splitting for hydrogen fuel generation, and other electrochemical processes for value-added chemical production to reduce or even eliminate greenhouse emissions. Further research and development of C-MFECs could revolutionize clean energy and environmental remediation technologies. In this talk, I will summarize some of our work on the development of C-MFECs for clean energy conversion and environmental remediation, along with an overview of recent advances, current challenges, and future perspectives in this exciting field.
