Center for Electrochemical Dynamics and Reactions on Surfaces (CEDARS)

CEDARS studies how electrons and protons move and how bonds form and break on the surface during the process of producing hydrogen from water. We combine precise methods for growing materials with various techniques like scattering and spectroscopy to examine the intermediate steps involved. We also use computer modeling based on fundamental principles. Our team is diverse and comes from different fields of study, including materials science, chemistry, and computational science.

Our Challenge

Using water to produce hydrogen, which is a clean and abundant energy source, is a secure method. However, the current method of producing hydrogen from water is slow and requires more energy than necessary. Scientists are not sure why this is the case because the process of splitting water into hydrogen and oxygen involves complex reactions. Our team of researchers has been formed to understand the step-by-step process of how these reactions occur, how catalysts work, and how they can improve the efficiency of producing hydrogen from water.

Community

In addition to our research, we also prioritize training and workforce development. We want to create an environment that equips the next generation of researchers with the skills needed to advance clean hydrogen production on a large scale. We believe that through collaboration and exchange, we can make significant progress in this important field.

Thrust 1

In Thrust 1, our focus is on understanding how different catalysts affect the process of splitting water. We want to know why some catalysts start the reaction faster than others. By studying metals and metal oxides, we aim to uncover the energy and dynamics involved in breaking apart water molecules. We will use advanced techniques like spectroscopy to observe the structure and changes that occur during the reaction.

Thrust 2

Thrust 2 is all about figuring out how the speed of the reaction is influenced by the surface properties and the environment of the catalyst. We will manipulate the surroundings of the catalyst and use different methods to study the chemical reactions happening on the surface. Our goal is to understand how electronic and chemical states can be adjusted to speed up the reaction and improve catalysis.

Thrust 3

In Thrust 3, we are focusing on the stability of the catalyst and how to prevent corrosion. We want to understand how the catalyst material changes during the reaction and the formation of chemical bonds. We will explore strategies like applying protective layers and controlling the timing of surface activation. By studying the behavior of the catalyst over multiple reaction cycles, we hope to uncover the connection between surface reconstruction and corrosion.
