New hydrogen production method created
COLUMBUS, Ohio, Aug. 25 (UPI) -- U.S. chemists at Ohio
State University say they have developed a catalyst that can very
efficiently convert ethanol and other biofuels into hydrogen.
Ohio State Professor Umit Ozkan said the new catalyst makes
hydrogen from ethanol with 90 percent yield, at a workable
temperature and using inexpensive ingredients since it doesn't
contain precious metals, such as platinum or rhodium.
"Rhodium is used most often for this kind of catalyst and it
costs around $9,000 an ounce," Ozkan said. "Our catalyst costs
around $9 a kilogram."
She said the newly developed catalyst could help make the
use of hydrogen-powered cars more practical in the future.
"Our research lends itself to what's called a 'distributed
production' strategy. Instead of making hydrogen from biofuel at a
centralized facility and transporting it to gas stations, we could
use our catalyst inside reactors that are actually located at the
gas stations," said Ozkan. "So we wouldn't have to transport or
store the hydrogen -- we could store the biofuel, and make hydrogen
on the spot."
Ozkan and doctoral students Hua Song and Lingzhi Zhang
presented the research last week in Philadelphia during a meeting of
the American Chemical Society.
