The products of homogeneous metal catalysis are ubiquitous in modern society, including pharmaceuticals, plastics, detergents, and more. While the structure and mechanism of homogeneous catalysts are generally well-understood, allowing a high degree of control, many industrially relevant homogeneous catalysts rely on rare and/or expensive metals, and so heterogeneous catalysts are used more often in industry because of their superior recoverability and stability.
The Griffin Group aims to improve sustainability in industry by exploring the following questions:
1) Can earth-abundant metals be used in place of precious metals?
2) Can non-invasive stimuli or changes in local chemical environment improve catalyst control and efficiency?
3) Can existing homogeneous catalysts be translated to heterogeneous systems to improve recyclability?
Catalysis is the central theme that ties together all of our research projects. Ultimately, it is our goal to improve sustainability in industrial organic synthesis by addressing shortcomings in homogeneous catalyst systems while adopting earth-abundant metal alternatives.
Identifying areas of improvement in a chemical reaction often requires a detailed understanding of how the reaction proceeds. Thus, our group is interested in investigating the structure and mechanism of the catalysts that we employ using a variety of techniques.
Our group is interested in how light interacts with catalysts and how this non-invasive stimulus can be used to improve catalytic efficiency or control reaction outcomes. We study these interactions using a variety of tools and methods.
Heterogeneous catalysts offer several practical advantages over homogeneous catalysts. We are particularly interested in the synthesis of new Metal-Organic Frameworks (MOFs) and their applications as heterogeneous catalysts for organic reactions. The tuneability and high internal surface area of these insoluble materials make them well suited for catalysis.
