Highly Stable and Active Catalyst for Sabatier Reactions
Highly active Ru/TiO2 catalysts for
Sabatier reaction have been developed.
The catalysts have shown to be stable
under repeated shutting down/startup
conditions. When the Ru/TiO2 catalyst is
coated on the engineered substrate
FeCrAlY felt, activity enhancement is
more than doubled when compared with
...

These materials could function while hotter and drier.
Polyoxyphenylene triazole sulfonic acid has been proposed as a basis for development of improved proton-conducting polymeric materials for solidelectrolyte membranes in hydrogen/air fuel cells. Heretofore, the proton-conducting membrane materials of choice have been exemplified by a family of perfluorosulfonic ...Read More >>
