Researchers from Rice University have discovered an efficient, robust way of drawing hydrogen and oxygen from water.

The researchers have developed a new catalyst of a cobalt-based thin film, which pumps out hydrogen and oxygen to feed fuel cells.

This from Rice University:

The inexpensive, highly porous material invented by the Rice lab of chemist James Tour may have advantages as a catalyst for the production of hydrogen via water electrolysis. A single film far thinner than a hair can be used as both the anode and cathode in an electrolysis device.

The new cobalt film is more efficient at producing hydrogen than other materials and is much cheaper than commercial platinum catalysts.

“It is amazing that in water-splitting, the same material can make both hydrogen and oxygen,” Tour said. “Usually materials make one or the other, but not both.”

The researchers aim to make this an environmentally friendly source of hydrogen and oxygen by applying alternating current from renewable energy sources to cobalt-based electrolysis.
