Researchers at the University of Cambridge in the U.K. are developing a low-cost cobalt catalyst they say could efficiently extract hydrogen from water at industrial production levels.
The scientists report that their catalyst appears to satisfy key challenges for such systems: low cost, high efficiency and the ability to work with pH-neutral water at room temperature while surrounded by oxygen molecules.
They concede their material exhibits "rather poor" stability. But they describe their work as a first step to producing "green" hydrogen. They also are developing a sunlight-driven water-splitting system.
The group reports its results HERE in the online journal Angewandte Chemie International Edition.
