Pulsed EPR Studies of Transition Metal-Exchanged Zeolites and Molecular Sieves
EMSL Project ID
2567
Abstract
In ongoing work in my laboratory, we are using CW EPR spectroscopy to study transition metal-exchanged zeolites and molecular sieves. Transition metal-exchanged zeolites are active catalysts for the selective catalytic reduction of nitric oxide and for selective oxidation reactions. So far, we have focused on measuring vanadium g and A values for vanadium-exchanged zeolites and molecular sieves. We have recently initiated studies of molybdenum-exchanged zeolites. We would also like to conduct pulsed EPR experiments at PNNL on these transition metal-exchanged zeolites. The pulsed EPR experiments will provide us with a more direct probe of transition metal-ligand interactions. The pulsed EPR experiments will allow us to address questions related to how the ligand interacts with the transition metal center and will provide insight into the identity of the ligands in the first coordination sphere of the transition metal center.
