Adsorption of HNCO on the reduced sample at 190K produced an absorption band at 2,170cm−1 attributed to NCO bonded to Ag. Annealing the adsorbed layer under continuous degassing, the 2,170cm−1 band gradually attenuated and at the same time a spectral feature at 2,300cm−1 due to Si-NCO developed. From these spectral changes it was inferred that NCO bonded to Ag spilt over onto silica.
