Combined sulfating and non-sulfating support to prevent water and sulfur poisoning of Pd catalysts for methane combustion

Chem Commun (Camb). 2010 Sep 14;46(34):6317-9. doi: 10.1039/c0cc00723d. Epub 2010 Jul 30.

Abstract

The appropriate combination of titania and silica, sulfating and non-sulfating support, respectively, results in Pd catalysts with improved water and sulfur tolerance in methane combustion. For the first time the catalyst recovers the initial activity after one cycle under lean-burn conditions without additional regenerating treatments.
