Features & Benefits


Sofnocat™ 514 technology combines promoted platinum, palladium and tin oxide, with unique support chemistry, to produce a highly active and effective oxidation catalyst.
Properties include:

  • Water tolerance
  • Low temperature performance
  • High mechanical strength
  • Low breathing resistance

Applications & Uses

Primary Application Areas

Safety, Gas processing


Sofnocat™ 514 removes harmful and unwanted gasses from a variety of applications.

Specifc uses include: Conversions of carbon monoxide in breathing gas filters Removal of hydrogen within enclosed environments Abatement of volatile organic compounds (VOCs) Obtaining ultra high purity carrier gasses for electronic component manufacture

Typical Conversion (%)

Carbon Monoxide (CO) 100 20 0.1 >50
100 20 0.2 >67
100 20 0.3 >80
1000 20 3 >95

Note: Hydrogen removal effciency is not routinely measured, however the half life is in the order of minutes. Sofnocat™ 514 can be successfully used to control hydrogen liberated during battery charging duty where long contact times are usually acceptable.
