The Water Gas Shift (WGS) reaction produces hydrogen from coal derived syngas. Several precious metals have been supported on aerogels and then tested for WGS activity. The present study explores iron aerogels and iron aerogels doped with 1% and 2% w/w palladium. The iron aerogels, synthesized using the propylene oxide method, were calcined at several temperatures. Their surface areas were measured at each calcination temperature. Palladium (1% and 2% w/w) was incorporated onto iron aerogels using the gas phase incorporation (GPI) technique. The WGS activity of the iron aerogels and iron aerogels doped with palladium was tested within the 150 ºC to 350 ºC range using a packed bed, six channel reactor. Addition of palladium onto iron aerogels increased the activity of the iron aerogel by a factor of 5 at 350 ºC. Palladium incorporation onto iron aerogels also increased the percent conversion of CO by a factor of 6 at 350 ºC.
