The three winners of the quiz with Prof. Niemantsverdriet
The second day of the workshop was filled with lectures which covered a lot of surface science techniques and case studies. Dr. Zhang Tianfu gave an overview lecture on surface science techniques; Dr. Lim Tingbin presented on the use of Scanning Tunneling Microscopy (STM) in surface reactivity studies; Prof. Niemantsverdriet focused on Temperature Programmed Reaction and Desorption; Dr. Ajin Cheruvathur and Dr. Yu Xin lectured on the Raman Spectroscopy and Reflection Absorption Infrared Spectroscopy (RAIRS) respectively; Dr. Zhang Chenghua gave a detailed description on a surface science case study about CO, H2 on Fe-based FT.
Dr. Zhang Tianfu’s talk, titled “How surface science techniques can help to understand the reaction mechanism”, introduced the basic processes in surface reactions related to catalysis, then briefly gave an overview of the plethora of surface science techniques used to study such reactions, and ended with a detailed illustration of how such techniques were used in uncovering the reaction mechanism of ammonia synthesis. In Dr. Lim Tingbin’s talk, titled “Studying Surface Reactivity by STM”, he presented the basic principle of STM and also lot of examples to explain how to use STM to study surface sites and molecular adsorbate reaction. Prof. Niemantsverdriet’s lecture, titled “Temperature Programmed Reaction and Desorption”, described the basic concept of TPD and its application. He especially emphasized on the TPD analysis methods and the application of TPD on uncovering reaction mechanism by supplying case study examples.
Dr. Ajin Cheruvathur’s lecture “Introduction to Raman Spectroscopy”, started from an introduction on theory background and instrumentation of Raman spectroscopy, and then followed with comparison of IR and Raman spectra, and some examples for the applications of Raman spectroscopy. Afterwards, Dr. Yu Xin followed with a similar technique in title “Reflection Absorption Infrared Spectroscopy”, where she explained the principle and instrumentation of RAIRS in detail, illustrated with RAIRS experimental results of molecules on metals surfaces with a few examples.
The last talk of the day, was “CO, H2 on Fe – Surface Science Studies” by Dr. Zhang Chenghua. In this lecture, he firstly gave a brief introduction on Fischer-Tropsch synthesis and the fundamental steps involved in the FT reaction, then he presented highly detailed work on the effects of O, C, S, and K on H2 and CO adsorption on Fe, with emphasis on the fundamental understanding of adsorbate-substrate interactions.
