Molybdenum-oxo catalyst offers cheap route to H2 from water

By Scott Jenkins |

A novel catalyst designed by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) and the University of California at Berkeley (www.berkeley.edu) has shown the ability to catalyze the electrolysis of water into hydrogen and oxygen, and is 70 times cheaper than platinum ($2,000/oz.), which has also been used to catalyze the reaction. In a recent paper in Nature, the research team reports that the catalyst does not require organic acids or other additives, and can operate in neutral water, as well as in the most abundant H2 source on earth, seawater. An inexpensive and efficient water-splitting catalyst could expand hydrogen’s role as a clean energy alternative in the future. Lead author Hemamala Karunadasa explains that the new proton reduction catalyst is based on a molybdenum-oxygen complex, and can generate hydrogen gas at the rate of 2.4 moles H2 per mole catalyst per second. These values represent lower bounds, the authors say, and “are significantly higher than any other reported metal catalyst for electrochemical hydrogen production from neutral water.” The catalyst has a pseudo-octahedral geometry, where the pentadentate ligand 2,6-bis(1,1-bis(2-pyridyl)ethyl)…
