high activity over a wide range of temperatures

excellent stability at high temperatures Resistance to sulfur containing gases to

about 10 ppm H₂S

Higher CO conversion percentage than CuZnO catalyst over wide range of temperatures (S. Swartz)

Life Time

Fuelcellmaterials.com reviewed next tech’s high temperature Pt/Ce catalyst and observed little loss in CO conversion % over 300 hrs continuous run time @ 400 C.

Life Time

Very little degredation over time. Little to no regeneration period needed.

As opposed to Cu-Zn-Al which reduce to about ½ co conversion % within 10 hrs (w/o regeneration) [Kim et al. 2005]

Regardless of form, the cost for Pt/ceria based catalyst is about 10$/g.

Comes in powder and pellet form from nextechmaterials.com

Only 100-150 mg needed per one test according to S. Swartz of Nextech materials
