Abstract

A quantum limit catalyst. The instant quantum limit catalyst is comprised of atomic aggregations whose dimensions correspond to the quantum limit. In the quantum limit, the atomic aggregations acquire structural configurations and electronic interactions not attainable in the macroscopic limit. The structural configurations possible in the quantum limit correspond to atomic aggregations having bond lengths, bond angles, topologies and coordination environments that differ from those found in the macroscopic limit. The electronic interactions possible in the quantum limit originate from wavefunction overlap and tunneling between atoms and lead to modifications in the magnitude and/or spatial distribution of electron density at catalytic sites to provide improved catalytic properties. Representative quantum limit catalysts include quantum scale atomic aggregations of metal atoms. Examples including catalysts derived from Fe, Mg, V and Co are disclosed. Catalytic properties are exemplified in the context of hydrogen storage.
