In this study, it was found that Pt particles could be obtained on a non-reducible support by weakening the interaction between the metal and support using oleic acid. The turnover frequency for catalyzing the hydrogenation of chlorinated nitrobenzene was three orders of magnitude higher than that of atomic platinum species.
The atomic dispersion of a noble metal with a reducible support has been reported to be beneficial for catalytic hydrogenation reactions. Conversely, we found that Pt particles (3-5 nm) could be obtained on the non-reducible support Al2O3 by weakening the interaction between the metal and support using oleic acid, and the turnover frequency of catalyzing the hydrogenation of chlorinated nitrobenzene could reach 3700 h(-1), which is three orders of magnitude higher than that of atomic platinum species.
