Platinum Ceria WGS catalyst

Nicholas DiPreta


Pgm catalysts
PGM Catalysts

  • Non pyrophoric- does not deactivate in presence of oxygen or water- in fact, studies have shown that 1% oxygen presence decrease deactivation

  • high activity over a wide range of temperatures

  • excellent stability at high temperatures

  • Resistance to sulfur containing gases to about 10 ppm H₂S


Temperature range
Temperature Range

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


Life time
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 time1
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]


Cost forms
Cost/ Forms

  • 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
