NOVEL METAL COMPLEX CATALYSTS AND USES THEREOF

摘要

The invention relates to novel metal complexes useful as catalysts in redox reactions (such as, hydrogen (H2) production). In particular, the invention provides novel transition metal (e.g., cobalt (Co) or nickel (Ni)) complexes, in which the transition metal is coupled with N,N-Bis(2-pyridinylmethyl)-2,2′-Bipyridine-6-methanamine (DPA-Bpy), 6′-((bis(pyridin-2-ylmethyl)amino)methyl)-N,N-dimethyl-2,2′-bipyridin-6-amine (DPA-ABpy), N,N-bis((isoquinolin-1-yl)methyl)(6-(pyridin-2-yl)pyridin-2-yl)methanamine (DIQ-Bpy), or a derivative thereof. The invention also relates to a method of producing H2 from an aqueous solution by using the metal complex as a catalyst. In certain embodiments, the invention provides a metal complex of the formulae as described herein.
