Co(II) and Cu(II) ion exchanged samples of Nafion were prepared, and a Co(II)- ZSM-5 zeolite was obtained. All of these sample were studied by diffuse reflectance spectroscopy both in the hydrated state and after dehydration under a dynamic vacuum. It was shown that the Co-containing samples could be dehydrated under rather mild thermal conditions. The dehydrated samples give distinct spectra for the Co(II) ions. However, the Cu-Nafion sample was difficult to dehydrate while maintaining the stability of the Nafion matrix. NO adsorption and decomposition studies are being initiated with these samples
