| Abstract: | We have studied nano-sized Au catalysts supported on Mg(OH)2 and TiO2 using 197Au Mössbauer spectroscopy. 197Au Mössbauer spectra observed for Au/Mg(OH)2 catalysts can be decomposed into one singlet with zero isomer shift and several doublets. One of the doublets shows an isomer shift that is typical for AuI, and other doublets are due to AuIII. The relative area of the AuI component shows the maximum value for a specimen calcined at 523 K, which also shows the highest catalytic activity. |
