摘要

Conclusions The oxygen chemisorption and FTIR indicate that the electronic structure of the Pt clusters is sensitive to the framework acidity. This sensitivity is not a result of electron transfer from the Pt clusters to the support as this would have bccn observable in the XANES data. All observations made thus far can be explained on the basis of change in the ionization potential of Pt. The ionization potential of Pt clusters increases as their size ...
