Iron and copper active sites in zeolites and their correlation to metalloenzymes
Abstract/Contents
- Abstract
- Metal-exchanged zeolites are a class of heterogeneous catalysts that perform important functions ranging from selective hydrocarbon oxidation to remediation of NOx pollutants. Among these, copper and iron zeolites are remarkably reactive, hydroxylating methane and benzene selectively at low temperature to form methanol and phenol, respectively. In these systems, reactivity occurs at well-defined molecular active sites. In this thesis, I discuss significant advances in the spectroscopic characterization of these active sites and their reactive intermediates. Site selective spectroscopy plays a critical role, making it possible to focus on active sites that exist within a distribution of inactive 'spectator' metal centers. Work presented here advances our understanding of the geometric and electronic structures of metallozeolites to the level attained in bioinorganic chemistry, enabling direct comparison of metallozeolites to functionally analogous Fe and Cu active sites in biology. Parallels and differences between metallozeolites and metalloenzymes are identified, leading to a number of new mechanisms to tune the performance of synthetic catalysts.
