On June 4th, Professor Ren Bin, a fellow of the International Society of Electrochemistry (ISE) and head of the innovation group of the Committee of the National Natural Science Foundation of China, visited the Hundred-year Chemistry Lecture Hall of Nankai University and gave a speech on the electrochemical technology of high Spatiotemporal resolution spectroscopy. Chen Jun, vice president of Nankai University, awarded Ren Bin the commemorative medal of the Hundred-year Chemistry Lecture Hall of Nankai University. More than 100 teachers and students from the Colleges of Chemistry and Physics attended the lecture.

The major challenge of electrochemical in-situ characterization lies in how to study the surface and interface process of electrochemistry with higher sensitivity and higher temporal and spatial resolution. Ren Bin said that he invented the electrochemical microscope based on surface-enhanced Raman spectroscopy, and reconstructed the electrochemical reaction current and potential information of the localized electrode by utilizing the change of Raman signal intensity in the process of electrochemical reaction. He also developed highly sensitive electrochemical in-situ dark-field spectroscopy on the basis of water mirror and electrochemical tip-enhanced Raman spectroscopy (EC-TERS) to study the structure and reaction process of electrochemical surface and interface at the nano-scale. Ren Bin took the dynamic chemical process of the electrochemical surface and interface, two-dimensional materials and the study of the surface reaction of bimetallic catalysts as examples to display the research paradigm of in-situ electrochemical spectroscopy to the teachers and students at the school. He also discussed the relevant academic issues with the audience and finished his speech amid tremendous applause.

The Hundred-year Chemistry Lecture Hall of Nankai University is one of the most significant commemorative activities of the 100th anniversary of founding the chemistry discipline of Nankai University. The activity aims to invite prestigious scholars of chemistry from home and abroad to deliver high-level academic lectures to facilitate the development of chemistry at Nankai University.
