Fastest Water Oxidation Catalyst Created

ATLANTA, March 16 (UPI) — U.S. chemists say they have developed the fastest homogeneous water oxidation catalyst known for use in making hydrogen fuel from water and sunlight.

Emory University researchers, in collaboration with the Paris Institute of Molecular Chemistry, said the carbon-free molecular water oxidation catalyst they developed is the fastest to date. “It’s like a home run compared to a base hit,” said Professor Craig Hill, who led the study. It “has really upped the standard from the other known homogeneous water oxidation catalysts.”


The research is a component of the Emory Bio-inspired Renewable Energy Center, which aims to mimic natural processes such as photosynthesis to generate clean fuel. The scientists said the next step involves incorporating their water oxidation catalyst into a solar-driven, water-splitting system.

Benjamin Yin, an undergraduate student in Hill’s lab, is the lead author of the U.S. Energy Department-funded study that is reported in the journal Science. Co-authors are Hill, Yurii Gueletii, Jamal Musaev, Zhen Luo and Ken Hardcastle.
