Abstract
The Pd/Al,O,catalyst displayed significant activity towards conversion of NO into N,and O,at T>1050° K. On modifying the catalyst with NaOH, the required operation temperature may be lowered to 900° K. The modified Pd/Al,O,may be used in stationary factories and power stations, as well as catalytic converters for abatement of NO,emission. Calorimetric and temperature-programmed-desorption studies revealed that observed catalytic activity at 900° K. resulted from a formation of interfacial sites which strongly adsorb NO molecules.
