SSE Weekly Colloquium | 理工学院系列研讨会邀请

The School of Science and Engineering is committed to creating a platform for students and faculty members to exchange ideas and explore cutting-edge research developments in various fields of science and engineering. Starting from 2021 fall, SSE will organize the "Weekly Colloquium" series of seminars every Friday. Each week, SSE will invite our faculty members and distinguished guest speakers from outside the University to conduct academic seminars.  

All students and faculty members are invited to join the weekly colloquium!

Abstract

For decades, people have been looking for an energy-efficient and sustainable method to produce future’s chemicals. Heterogeneous single-atom catalysts (SACs) with atomic dispersion of robust, well-characterized active centers are highly desirable in mimicking the homogeneous pathway for extremely high activity and chemoselectivity. SACs are also advantageous in their maximum metal utilization efficiency and atomically precise coordination compared to other subnanometric variants (clusters, nanoparticles, etc.). By explaining the concept of SACs, I will introduce how modern scientists understand chemical reactions at the atomic level via extremely high resolution microscopic techniques and operando spectroscopic methods. I will also detail the state-of-the-art approaches to regulating chemical reactions via catalyst designs. Finally, I will identify the technical barriers that need to be overcome in this area and offer my perspective on emerging strategies for mass production, rapid screening, and AI-assisted catalyst designs.

The Speaker

Zhongxin CHEN is currently a tenure-track assistant professor in the School of Science and Engineering at The Chinese University of Hong Kong. He obtained his B.Sc & M.Sc. in polymer science at Fudan University in 2011 and 2014 and his Ph.D. degree with Professor Loh Kian Ping in chemistry at the National University of Singapore in 2018. During these years, he has developed a variety of heterogeneous catalysts to transform small molecules into value-added fine chemicals by electrocatalysis, photocatalysis, and organic catalysis. His particular focus involves the atomic-level regulation of the coordination environment of catalysts and understanding of the catalytic cycle by means of advanced microscopic and spectroscopic techniques (such as STEM and operando XAS). Dr. CHEN has published 28 top-tier papers as the first/co-first or corresponding author, including Nat. Commun., Adv. Mater., Sci. Adv., J. Am. Chem. Soc., ACS Catal., Adv. Funct. Mater. and Acc. Mater. Res. etc., and applied for 7 international or US patents. He is the co-author of more than 90 SCI journal papers and currently holds an H-index of 44 and a citation of > 6600 in Google Scholar.
