Kyoung-Shin Choi is a Professor of Chemistry at the University of Wisconsin-Madison.[4][5] Choi's research focuses on the electrochemical synthesis of electrode materials, for use in electrochemical and photoelectrochemical devices.

Early life and education

Choi studied piano at Yewon Middle School, Korea's first middle school dedicated to the arts. In high school, she attended an interesting science class which inspired her to become a scientist.[6][7] Choi attended college at Seoul National University in South Korea, earning her B.S. in 1993 and M.S. in 1995. Initially in the department of pharmacy, she later switched over to and majored in food and nutrition, with a minor in chemistry.[6][7] She worked with Prof. Jin-Ho Choy on the crystal structure, pressure-induced phase transitions, and magnetism of chromium-niobium oxide materials that adopt the double perovskite structure.[8] Choi says that although there was was prejudice against female students majoring in the pure sciences when she studied in Korea at the time, she pushed through because of her desire to conduct research in chemistry.[6][7]

For her doctoral studies, Choi emigrated to the United States at the age of 26 in 1995, despite not being able to speak English at the time.[6][7] She worked at Michigan State University in the laboratory of Prof. Mercouri G. Kanatzidis, earning her Ph.D. in chemistry in 2000. Her graduate work focused on the synthesis of various solid state antimony and bismuth-containing chalcogenides[9][10][11] using the "molten polychalcogenide salt method."[12]

Choi then conducted postdoctoral studies from 2000 to 2002 at the University of California, Santa Barbara with Prof. Galen D. Stucky and Prof. Eric W. McFarland. Her postdoctoral research concerned the electrochemical synthesis of nanostructured thin films.[13][14]

Independent career

Choi began her independent career at Purdue University as an Assistant Professor in 2002, and was later promoted to Associate Professor. She was a Visiting Scholar at the National Renewable Energy Laboratory in 2008. In 2012, she moved to University of Wisconsin-Madison as a full Professor of Chemistry.[15]

Choi has served as an Associate Editor of the journal Chemistry of Materials since 2014.[16]

Research

The Choi research group studies electrodes and catalysts for use in photoelectrochemical and electrochemical applications. Earlier work in the group has included the crystallization of cuprous oxide in various morphologies, in which the authors utilized electrochemistry to control the crystallization process and resultant crystal morphologies.[17][18][19]

The Choi group has extensively studied bismuth vanadate, a photoanode for light-driven water splitting. This material suffers from facile bulk electron-hole recombination, but by combining the bismuth vanadate catalyst with oxygen-evolution catalysts such as FeOOH and NiOOH, Choi and coworkers were able to minimize this deleterious process and achieve higher catalytic efficiencies.[20][21] The Choi group has also studied the stability of the bismuth vanadate catalyst,[22] as well as the effects of surface composition on the interfacial energetics of photoelectrochemical catalysis.[23]

In one report, Choi and coworkers developed a photoelectrochemical cell (PEC), a device that can split water into hydrogen and oxygen given inputs of light and electricity. PECs are promising devices for hydrogen production, for use in a hydrogen economy. However, the anodic reaction, the oxygen evolution reaction (OER), is slow and limits the overall process. To sidestep this problem, Choi and coworkers paired the hydrogen evolution reaction (HER) with oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA).[24] This allows them to generate FDCA, a valuable commodity chemical used in plastic production, from HMF, which can be derived from cellulose.[25]
