SO2 Stabilization of Dispersed Silver on Alumina at High Temperatures
BACKGROUNDSilver catalysts can be used for ethylene epoxidation and appear promising for selective catalytic reduction (SCR) of NOx with hydrocarbons. For example, silver catalysts have potential application in SCR of NOx with hydrocarbons or oxygenates to remove nitrogen oxides from various exhaust gas effluents. The promise of the silver catalysts...

Novel Catalysts with Substantially Reduced Metal Content and Undiminished Activity
SummaryResearchers at Tufts University have discovered a novel method to make effective catalysts for fuel cells using only a fraction of the precious metals typically used, substantially lowering manufacturing costs. The resulting catalyst is virtually free of microcrystalline metal particles and just as efficient as traditional catalysts.BackgroundFuel...
