Title Postdoctoral Fellow, Chemistry (Catalyst Dev)

Appointment Status Non-Tenure Track Department IU Bloomington Chemistry Position Summary

Department Information:

The Department of Chemistry consists of a well-rounded research community with cutting-edge expertise in a wide variety of modern disciplines including analytical chemistry, organic chemistry, inorganic chemistry, physical chemistry, materials chemistry, and biochemistry.

Job Summary:

Prof. Steven Tait and Prof. Ken Caulton in the Department of Chemistry at Indiana University are accepting applications for a postdoctoral research position on a joint collaborative project, which is supported by the U. S. Department of Energy. The position offers an opportunity to work on an interdisciplinary project that targets the rational design of metal-ligand single atom heterogeneous catalysts.

Improved efficiency in industrial chemical processes requires new catalyst development to satisfy increasing global chemical demands and energy challenges. Traditional heterogeneous catalysts, usually consisting of metal nanoparticles on an oxide support, are effective for many processes, but have limitations for chemical conversions that require a high degree of reaction selectivity. In this work, the uniformity and structure of single transition metal atom catalytic centers is determined by rationally tailored molecular ligands to ensure high reactivity, product selectivity, and stability. Catalysts will be characterized before, during, and after catalytic reactions to (1) examine and improve high selectivity, (2) design higher stability in metal-ligand single atom catalysts, and (3) test this class of catalysts for several reactions. The reactions studied will include hydrogenation, hydrosilylation, and other industrially important reactions that probe the metal-ligand catalyst performance. The central theme of the work is to rationally design, synthesize, characterize, and test new catalysts on high surface area oxide supports. There are several research directions of this work going on in our laboratory and the successful postdoctoral candidate is expected to focus on one or more of these directions and interface with collaborating group members in the other areas. These directions include (a) synthesis of novel ligands for metal coordination, (b) synthesis of supported single-atom catalysts, © characterization of catalysts on high surface area supports, (d) flow reactor chemistry, (e) electron microscopy and photoelectron spectroscopy, and (f) surface analysis of analogous model catalyst systems in ultra-high vacuum using X-ray photoelectron spectroscopy and scanning tunneling microscopy. Catalyst performance will be tested in flow reactors and the catalyst characterization will be done using state-of-the-art spectroscopy and microscopy tools at Indiana University and at national Department of Energy user facilities. These will allow for deeper understanding of the interactions that determine performance and selectivity, especially the balance between metal-ligand and metal-support interactions. This will lead to new understanding in heterogeneous single-atom catalysts that will enable transformative advances in catalysis and development of new reaction chemistries.

Applicants will emerge with a skill set that is relevant to academia and industry. This position will allow for development and training in metal- organic chemistry, heterogeneous catalysis, and surface science, which will provide a strong foundation for future career development in each of these fields and in other interdisciplinary sciences. Trainees will receive regular guidance to ensure progress is made toward their career goals, regardless of whether trainees are pursuant of traditional or alternative careers. Trainees are also afforded the scheduling flexibility needed to maintain an appropriate work life balance. The trainee will be involved in experiment design and planning, supervision of graduate students, synthesis, and characterization, including occasional measurements at Argonne National Laboratory and other national user facilities.

Basic Qualifications

Ph.D. in chemistry or chemical engineering at time of appointment (or related discipline, if applicable).

Prior research experience in at least one of (1) metal-organic chemistry and ligand synthesis, (2) surface science, or (3) heterogeneous catalysis. Applicants are not expected to have experience in all of those fields but should have the ambition to develop skills in this interdisciplinary training program that bridges those fields.
