Abstract
While platinum supported on one-atomic layer Niobium oxide which was chemically attached on a silica surface did not exhibit an SMSI phenomenon unlike usual Nb2O5-supported Pt, the ethene hydrogenation activity of the catalyst reduced at 773 K was much higher than a SiO2-supported Pt catalyst. Another interesting feature is that the activity was reversibly enhanced or depressed as a function of pre-evacuation temperature.Keywords
