Chemistry is truly the central science and underpins much of the efforts of scientists and engineers to improve life for humankind. TheMIT Department of Chemistryis taking a leading role in discovering new chemical synthesis, catalysis, creating sustainable energy, theoretical and experimental understanding of chemistry, improving the environment, detecting and curing disease, developing materials new properties, and nanoscience.
The Chemistry Education Office staff is responsible for administering the educational programs in the Department of Chemistry. Students can find answers to many questions about the undergraduate and graduate programs on the department website, and they are encouraged to stop by and see the staff in the office located in 6-205.
The student-run outreach programs in the Department of Chemistry aim to bring the excitement of chemical sciences to the community through lively demonstrations designed to illustrate a broad range of chemical principles. Graduate students visit science classes in high schools and middle schools in the Greater Boston area with a view to demystifying chemistry through hands-on experiments. ClubChem, an undergraduate chemistry organization, conducts Chemistry Magic Shows for elementary schools and youth programs in the Greater Boston area.

Competition between H and CO for Active Sites Governs Copper‐Mediated Electrosynthesis of Hydrocarbon Fuels Dr. Marcel Schreier, Dr. Youngmin Yoon, Megan N.

Abstract: The dynamics of carbon monoxide on Cu surfaces was investigated during CO reduction, providing insight into the mechanism leading to the formation of hydrogen, methane, and ethylene, the three key products in the electrochemical reduction of CO2. Reaction order experiments were conducted at low temperature in an ethanol medium affording high solubility and surface‐affinity for carbon monoxide. Surprisingly, the methane production rate is suppressed by increasing the pressure of CO, whereas ethylene production remains largely unaffected. The data show that CH4 and H2 production are linked through a common H intermediate and that methane is formed through reactions among adsorbed H and CO, which are in direct competition with each other for surface sites. The data exclude the participation of solution species in rate‐limiting steps, highlighting the importance of increasing surface recombination rates for efficient fuel synthesis.
Research in the Surendranath Group is focused on addressing global challenges in the areas of chemical catalysis, energy storage and utilization, and environmental stewardship. Fundamental and technological advances in each of these areas require new methods for controlling the selectivity and efficiency of inner-sphere reactions at solid-liquid interfaces. Their strategy emphasizes the bottom-up, molecular-level, engineering of functional inorganic interfaces with a current focus on electrochemical energy conversion.
