Abstract
Transition metal ions (Cu +, Ag +) incorporated within the cavities of zeolites by an ion-exchange method exhibit unique photoluminescence under UV irradiation due to the inner shell type electronic transition (d 9s 1 → d 10). Detailed photoluminescence investigations revealed that the transition metal ions exist in highly dispersed state with linear 2 coordination sphere and interact with NO x (NO and N 2O) in their photoexcited states. In fact, Cu + and Ag + ions within zeolites show an efficient and unique photocatalytic performance for the decomposition of NO into N 2 and O 2 at ambient temperature. Detailed studies of the interaction of NO x with the excited states of these metal ions indicated that an electron transfer from the s orbital of the excited state of Cu + or Ag + ions into the π ∗ antibonding orbital of NO x initiates the decomposition of NO x into N 2 and O 2.
