They have an amorphous, random structure like those of silica aerogels. “Making the aerogels from gels is easy,” explains Kanatzidis. “The trick is creating the gels in the first place.” The researchers have relied on platinum chemistry to form the gels. To reduce costs, they now are making gels without using the precious metal, he notes, and the aerogels derived from these maintain the performance of platinum versions. The next step is to make many more variants. Up to as 100 will be produced within the next year, hopes Kanatzidis. The aerogels also may be able to play a role in purification of gases such as hydrogen. here, though, the mechanism would be selective permeability, says Kanatzidis. “The aerogels may offer unique permeability.” hydrogen purification will be the main focus of such efforts, which should take place over the next year. “When people talk about the hydrogen economy, one of the big questions they’re asking is ‘can you make hydrogen pure enough that it doesn’t poison the catalyst?’,” chupas explains. “The high surface area also makes you think of catalysis,” adds Kanatzidis. it’s possible to include active sites in the structure of the aerogel, he notes. so far, work has been done on a lab scale (figure 1) but there’s no limitation to scale up of the aerogels, he says. september 2007 • 15 % http://www.chemicalprocessing.com
