Our lab is a place where "molecular architects" come together to design molecules for catalytic purposes. We don't just aim to create effective catalysts, but we strive to understand why they work the way they do, whether through successful attempts or unexpected results. We are constantly learning and revising our strategies, striving to "think like molecules."

One of our primary focuses is on the element bismuth, which is the heaviest main-group metal with no radioactivity. While transition metals have been widely studied for catalysis, the use of main-group metals for catalysis, especially the ones involving redox steps, are less explored. Our lab is always investigating new molecular compounds containing bismuth as potential catalysts for chemical transformations. We are particularly interested in synthesizing bismuth-based compounds for catalysis powered by electricity, i.e. electrocatalysis, using renewable electricity as the energy source instead of burning fossil fuels. Currently, we study two avenues along this topic: (1) using bismuth as the supporting ligand for transition metals and study their structures, electrochemical properties, and potentially catalytic reactivities; (2) synthesizing non-trigonal bismuth-centered compounds and study their structures and redox properties.

As a student in our lab, you will gain invaluable knowledge across a broad spectrum of fields, including renewable energy sciences, chemical catalysis, synthesis, and electrochemistry. You will also learn practical skills such as organic and inorganic synthesis under normal or air-free conditions, molecular structural determination, electrochemical techniques, electrode preparation, and catalytic analysis. We welcome undergraduates who are passionate about these research directions to discuss possible research opportunities with us. We are excited to see what we can achieve together!
