Education

After earning his Bachelors of Science in chemistry from Nanjing University in 1982, [1] Chen was selected by the China–USA Chemistry Graduate Program (CGP) for graduate studies in the US. [2]  

He received his Ph.D. in chemistry at the University of Pittsburgh in 1988 under the guidance of American surface scientist John Yates. [1] Chen then became an Alexander von Humboldt Postdoctoral Fellow [1] 1988–1989 at Forschungszentrum-Julich, Germany, where his research advisor was Harald Ibach. [2]

Professional career

Upon completion of his postdoctoral position in Germany, Chen went to work for the Exxon Corporate Research Laboratory as a staff scientist (1990–1998) and spokesperson for the Exxon U1A Synchrotron Beamline at Brookhaven National Laboratory (1994–1998). [2]

In 1998 he began his academic career at the University of Delaware. [3]  While at Delaware, in 2008 he was named the Claire D. LeClaire Professor of Chemical Engineering [3] and served several leadership roles including director of the Center for Catalytic Science and Technology (CCST) [3] and interim director of the University of Delaware Energy Institute (UDEI). [2]

In 2012, Chen moved to Columbia University, where he became the Thayer Lindsley Professor of Chemical Engineering. [4] He has also held a joint appointment at the chemistry department of Brookhaven National Lab since 2012. [2]

Chen has also been the co-founder and director of the Synchrotron Catalysis Consortium since 2005, [2] chair of the Catalysis Division of the American Chemical Society 2014–2015, [2] president of the North American Catalysis Society since 2017, [2] and associate editor of ACS Catalysis since 2016. [2]

Research

Chen has made many contributions to the understanding and development of novel catalytic and electrocatalytic materials, including bimetallic catalysts, [5] [6] [7] transition metal carbides, [8] [9] [10] and metal-modified carbide catalysts. [11] [12] [13] Chen and his research group have made many discoveries relating to monolayer (ML) bimetallic catalysts, which are tunable materials where a single atomic layer (i.e. monolayer) of one metal is deposited on the surface or subsurface of a second material. [14] Chen has developed these and other catalytic materials for a wide range of applications, including in developing tunable, low-cost (electro)catalysts for the production and use of clean fuels such as hydrogen (made from water electrolysis), [15] [16] nitrogen-based fuels, [17] [18] and methanol or CO (made from CO2). [19] [20] [21]

Some of Chen's research efforts involve a combination of theory and ultra-high vacuum (UHV) surface science tools to gain fundamental understanding of the chemical, physical, and electronic structures of the catalytic materials he studies. [22]   Chen's research also commonly relies on X-ray synchrotron techniques, such as X-ray Absorption Spectroscopy (XAS) to better understand the atomic structure of catalytic and electrocatalytic materials under reaction conditions. [23] As of 2024, Chen has been an inventor or co-inventor of over 20 United States patents and published over 500 peer-reviewed papers (h-index=114). [24]

<span class="mw-page-title-main">Catalysis</span> Process of increasing the rate of a chemical reaction

Catalysis is the increase in rate of a chemical reaction due to an added substance known as a catalyst. Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst.

<span class="mw-page-title-main">Hydrogenation</span> Chemical reaction between molecular hydrogen and another compound or element

Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces double and triple bonds in hydrocarbons.

<span class="mw-page-title-main">Heterogeneous catalysis</span> Type of catalysis involving reactants & catalysts in different phases of matter

Heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products. The process contrasts with homogeneous catalysis where the reactants, products and catalyst exist in the same phase. Phase distinguishes between not only solid, liquid, and gas components, but also immiscible mixtures, or anywhere an interface is present.

Nanomaterial-based catalysts are usually heterogeneous catalysts broken up into metal nanoparticles in order to enhance the catalytic process. Metal nanoparticles have high surface area, which can increase catalytic activity. Nanoparticle catalysts can be easily separated and recycled. They are typically used under mild conditions to prevent decomposition of the nanoparticles.

<span class="mw-page-title-main">Electrocatalyst</span> Catalyst participating in electrochemical reactions

An electrocatalyst is a catalyst that participates in electrochemical reactions. Electrocatalysts are a specific form of catalysts that function at electrode surfaces or, most commonly, may be the electrode surface itself. An electrocatalyst can be heterogeneous such as a platinized electrode. Homogeneous electrocatalysts, which are soluble, assist in transferring electrons between the electrode and reactants, and/or facilitate an intermediate chemical transformation described by an overall half reaction. Major challenges in electrocatalysts focus on fuel cells.

The electrochemical promotion of catalysis (EPOC) effect in the realm of chemistry refers to the pronounced enhancement of catalytic reactions or significant changes in the catalytic properties of a conductive catalyst in the presence of electrical currents or interfacial potentials. Also known as Non-faradaic electrochemical modification of catalytic activity (the NEMCA effect), it can increase in catalytic activity (up to 90-fold) and selectivity of a gas exposed electrode on a solid electrolyte cell upon application of a potential. This phenomenon is well documented and has been observed on various surfaces (Ni, Au, Pt, Pd, IrO2, RuO2) supported by O2−, Na+ and proton conducting solid electrolytes.

Heterogeneous gold catalysis refers to the use of elemental gold as a heterogeneous catalyst. As in most heterogeneous catalysis, the metal is typically supported on metal oxide. Furthermore, as seen in other heterogeneous catalysts, activity increases with a decreasing diameter of supported gold clusters. Several industrially relevant processes are also observed such as H2 activation, Water-gas shift reaction, and hydrogenation. One or two gold-catalyzed reactions may have been commercialized.
