Catalyst support structures facilitate high-temperature fuel reforming

CHAMPAIGN, Ill. -- The catalytic reforming of liquid fuels offers an attractive solution to supplying hydrogen to fuel cells while avoiding the safety and storage issues related to gaseous hydrogen. Existing catalytic support structures, however, tend to break down at the high temperatures needed to prevent fouling of the catalytic surface by soot.

Now, researchers at the University of Illinois at Urbana-Champaign have developed porous support materials that can withstand the rigors of high-temperature reforming of hydrocarbon fuels.

"These novel materials show great promise for the on-demand reforming of hydrocarbons such as diesel fuel into hydrogen for portable power sources," said Paul Kenis, a professor of chemical and biomolecular engineering at Illinois and a corresponding author of a paper to appear in the August issue of the journal Advanced Functional Materials.

To be useful for hydrocarbon fuel reforming, a catalyst support must have a high surface area, be stable at high temperatures, and possess a low pressure drop.

"Our new materials satisfy all three key requirements," said Kenis, who also is a researcher at the Beckman Institute for Advanced Science and Technology. "They have a large surface area created by a network of interconnected pores. They can operate at temperatures above 800 degrees Celsius, which prevents the formation of soot on the catalytic surfaces. And they have a low pressure drop, which means it takes less pressure to push the fuel through the catalyst."

To fabricate the supports, the researchers begin by placing a polydimethylsiloxane (PDMS) mold onto a flat surface, forming a channel about 500 microns wide that is open at both ends. A slurry containing polystyrene spheres 50 nanometers to 10 microns in diameter is then allowed to flow into the channel from one end by capillary action.

"Once the slurry reaches the other end of the channel, the spheres begin to pack together as a result
