Developing computational tools to understand the mechanism of CO2 reduction by bio-inspired catalysts
Project Goals and Description:
One way to mitigate the ever-increasing concentration of carbon dioxide in the earth’s atmosphere is to develop carbon recycling catalysts. Such catalysts would capture and convert carbon dioxide waste from fossil fuels into value-added products. This work aims to explore the viability of iron-sulfur clusters as potential carbon recycling catalysts. These catalysts offer several advantages, including being composed of earth-abundant elements and operating under mild conditions.
Dr. Morrison will work with the student to develop a solid understanding of catalysis by iron-sulfur clusters. Dr. Gomez-Gualdron will train the student to develop computational methods that can be used to probe the mechanism of CO2 reduction by iron-sulfur clusters. Results will be analyzed by the student and presented on a weekly basis to Dr. Morrison and Dr. Gomez-Gualdron, both of whom will help guide the trajectory of the project.
Grand Challenge: Develop carbon sequestration methods.

The student should have a strong background in chemistry to grasp the details of chemical mechanisms and apply this knowledge to developing computational tools and interpreting results. Computational experience is not required, but it will be helpful to be familiar with Linux systems.
TIME COMMITMENT (HRS/WK)
The student will work closely with Dr. Gomez-Gualdron to learn techniques in computational chemistry. The student will also work with Dr. Morrison to become in expert in catalysis by Fe-S clusters, which is necessary to develop the computational tools and interpret the results. The student will attend weekly collaboration meetings with Dr. Gomez-Gualdron and Dr. Morrison. These meetings will be used to discuss the student’s progress and the project trajectory.
