Researchers Create Model for Synthetic Hydrogen Catalyst Using Low Cost Materials

wiki hydrogenaseResearchers at the University of Illinois have created a synthetic catalyst model of the active hydrogen producing site of a naturally occuring enzyme based on 'cheap and plentiful building blocks – iron, nickel and sulfur.' 

The results could achieve the catalytic performance seen in rare and expensive metals such as platinum, and further humankind's ability to use nanostructured systems to elegantly manipulate the interactions of carbon, hydrogen, oxygen, electrons, photons and metals to enable new forms of energy production, storage and conversion.

“Nature relies on a very elaborate architecture to support its own ‘hydrogen economy,’ ” said Chemistry Professor Thomas Rauchfuss, a professor of  and corresponding author of the paper. “We cracked that design by generating mock-ups of the catalytic site to include the substrate hydrogen atom.”

Manipulating Natural Molecular Building Blocks
Enzymes are proteins that facilitate chemical reactions via catalysis.  Today, human beings know very little about the molecular magic of hydrogen producing enzymes (known as 'hydrogenase') and the complex reactions that occur inside the core reaction sites.

Developing accurate models of these activation sites is the first step towards developing low cost synthetic catalysts that can break the bonds of oxygen and hydrogen or carbon and hydrogen. The Illinois team is the first to model a nickel-iron structure with the use of a key link or bridge (hydrideligand).
