Copper promises cheaper, sturdier fuel cells
Date:11/22/2013

DURHAM, N.C. -- Copper adorns the Statue of Liberty, makes sturdy, affordable wiring, and helps our bodies absorb iron. Now, researchers at Duke University would like to use copper to transform sunlight and water into a chemical fuel.

Converting solar energy into storable fuel remains one of the greatest challenges of modern chemistry. One of the ways chemists have tried to capture the power of the sun is through water splitting, in which the atoms of H2O are broken apart so the hydrogen may be collected and used as fuel. Plants do this naturally through photosynthesis, and for half a century, scientists have tried to recreate that process by tinkering with chemical catalysts jumpstarted by sunlight.

Indium tin oxide (ITO) is one material they've commonly tried to use. Researchers prefer it for its transparency -- which allows sunlight to pass through and trigger the water-splitting reactions -- and its ability to conduct electricity. But ITO is far from an ideal material.

"Indium is not very abundant," said Ben Wiley, assistant professor of chemistry at Duke University. "It is similar in abundance to silver in the earth's crust." As a result, solar fuel cells using ITO will likely remain expensive and uncompetitive with conventional energy sources like coal and natural gas, he said.

Wiley's lab has created something they hope can replace ITO: copper nanowires fused in a see-through film. The team -- including two postdoctoral researchers, a graduate student, and a former graduate student from Duke -- published their new approach last month in the chemistry journal Angewandte Chemie.

Copper is 1000 times more plentiful and 100 times less expensive than indium. Copper nanowire catalysts also cost less to produce than their ITO counterparts because they can be "printed" on pieces of glass or plastic in a liquid ink form, using a machine that functions much like a printing press. ITO production, by contrast, req
