Highly efficient oxygen catalyst found (MIT)
A team of researchers at MIT has found one of the most effective catalysts
ever discovered for splitting oxygen atoms from water molecules — a key
reaction for advanced energy-storage systems, including electrolyzers, to
produce hydrogen fuel and rechargeable batteries. This new catalyst liberates
oxygen at more than 10 times the rate of the best previously known catalyst of
its type.
The new compound, composed of cobalt, iron and oxygen with other metals,
splits oxygen from water (called the Oxygen Evolution Reaction, or OER) at a
rate at least an order of magnitude higher than the compound currently
considered the gold standard for such reactions, the team says. The compound’s
high level of activity was predicted from a systematic experimental study that
looked at the catalytic activity of 10 known compounds.
The team, which includes materials science and engineering graduate student
Jin Suntivich, mechanical engineering graduate student Kevin J. May and
professor Yang Shao-Horn, published their results in _Science_ on Oct. 28.
The scientists found that reactivity depended on a specific characteristic:
the configuration of the outermost electron of transition metal ions. They
were able to use this information to predict the high reactivity of the new
compound ...
