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, heterogeneous catalysts are used more often in industry due to their superior recyclability and stability. In addition, many homogeneous catalysts used in industry rely on rare and/or expensive metals.
Our research 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?
