Studies on the deactivation and activation of palladium impregnated carbon catalyst for environmental applications

Palladium impregnated activated carbon (Pd/C) is an important catalyst for room temperature removal of carbon monoxide (CO). However, Pd/C are prone to deactivation, and reactivation for re-use of the catalyst becomes necessary from an economic point of view. Reactivation of Pd/C can be achieved by extracting the metal in a suitable media and subsequent re-impregnation on carbon support followed by liquid media reduction. Another method is by...
