NO decomposition in non-reducing atmospheres. Technical progress report, September 1996--November 1996
During this quarter, four additional samples of Co(II) ion exchanged erionite were prepared and shown to contain 0.002, 0.12, 0.30, and 1.3 wt% Co(II). These samples, as well as the five previously prepared and studied, were investigated by diffuse reflectance spectroscopy (DRS) studies to probe the state of the Co(II) cation in erionite zeolites and whether the zeolites were completely dehydrated at 350{degrees}C and 525{degrees}C. By comparing spectra as a function of Co(II) content and temperature of dehydration and by using second derivative mode analysis, it was shown that the Co(II) cations occupy three different sites in the erionite structure. DRS studies are underway to determine if Co(II) cations in all of these sites are accessible to ligands such as CO and ethylene.
