Research

Our group carries out research in inorganic and organometallic chemistry to address broad scientific challenges in today鈥檚 world. From the activation of small molecules relevant to energy storage and utilization to the efficient conversion of abundant chemical feedstocks, compounds containing transition metals have found applications as catalysts (compounds that increase the rate of chemical reactions) for a broad variety of chemical transformations. In our group, we design transition metal complexes鈥揷ompounds in which organic molecules (called ligands) support transition metal atoms, enabling and sometimes directly participating in their reactivity鈥揳s candidate catalysts for various reactions, and study their properties and reactivity using tools typical of the inorganic chemistry toolbox, including spectroscopy and electrochemistry. Two of our current projects focus on compounds containing rhodium, a metal with well-known catalytic properties. In one of these projects, we are aiming to develop complexes that replicate rhodium鈥檚 ability to make and/or break chemical bonds by undergoing two-electron changes in oxidation state with cheaper, more abundant metals. The second project takes a complementary approach, aiming to improve the activity of known rhodium catalysts and limit the excess energy required to operate them, thereby enhancing their efficiency and lowering the amount of these catalysts that is required for various applications. A third project focuses on a family of catalysts based on ruthenium鈥搑hodium鈥檚 neighbor on the periodic table. In this project, we are employing electrochemical methods to explore the behavior of ruthenium compounds and determine the correlation between the structure of the supporting ligands and the ability of ruthenium to transfer electrons. All these projects rely on critical contributions from F&M undergraduate students, who participate in the design, synthesis, and characterization of the target complexes and the studies of their reactivity via spectroscopic and electrochemical methods. Through this work, students in our group develop fundamental skills in carrying out manipulations typical of the inorganic laboratory, including the use of air-free techniques, in obtaining and analyzing data from various instrumental techniques, in exploring the primary literature, and in presenting their work to their peers and to the broader scientific community in written and oral forms.
