Breakthrough in designing cheaper, more efficient catalysts for fuel cells
Date:2/23/2012

University of California, Berkeley, chemists are reimagining catalysts in ways that could have a profound impact on the chemical industry as well as on the growing market for hydrogen fuel cell vehicles.

Catalysts are materials typically metals that speed up chemical reactions and are widely used in the synthesis of chemicals and drugs. They also are employed in automobile catalytic converters to change combustion chemicals into less-polluting emissions and in fuel cells to convert water into hydrogen.

The problem with catalysts, however, is that chemical reactions occur only at edges of or defects in the material, while the bulk of the metal often expensive platinum is inactive and wasted.

In an article appearing this week in the journal Science, UC Berkeley chemists show how to construct a catalyst composed only of edges and demonstrate that it can catalyze the production of hydrogen from water as readily as the edges and defects in regular catalysts.

"This is a conceptual advance in the way we think about generating hydrogen, a clean-burning fuel, from water, a sustainable source," said Christopher Chang, associate professor of chemistry and Howard Hughes Medical Institute Investigator at UC Berkeley. "Our new catalyst is just first generation, but the research gives us and the community a path forward to thinking about how to increase the density of functional active sites so that molecules and materials can be more effective catalysts."

At the moment, creating these catalysts in the lab is not cheaper than using traditional catalysts, but efforts by Chang and others to simplify the process and create materials with billions of active sites on a ridged wafer much like a Ruffles potato chip could allow cheaper, commercially viable fuel cell catalysts.

"The development of new earth-abundant catalysts for water splitting is an essential component of the global effort to move away from fossi
