Homogeneous Catalytic Production of Hydrogen and Other Molecules from Water-DMF (N-Dimethylformamide) Solutions

摘要

The reaction between water and DMF at 100 C under nitrogen (<1 atm) mediated by platinum, ruthenium, osmium, rhodium or iridium complexes leads to the evolution of H2, CO2, and CO as a minor product; Me2NH is also obtained, but it reacts in situ with one half of the CO2 produced to yield (Me2NH2)+(Me2NC(O)O)-. The various possible steps in this complex catalytic system are briefly examined. We wish to report a non-photochemical, non-electrochemical catalysis of hydrogen evolution from aqueous solutions at mild conditions. Keywords: Water carbon dioxide. (kr)
