Platinum lineshapes

We describe in some detail the techniques of nuclear magnetic resonance which are used for studying alumina-supported platinum catalysts. In particular, we describe the spin-echo technique from which the Pt lineshape can be obtained. We also discuss spin echo double resonance between surface Pt and chemisorbed molecules and show how the NMR resonance of the surface Pt can be separately studied. We present examples of experimental data and discuss their interpretation. [Pg.377]

Slichter, Sinfelt, and co-workers have opened this line of research some two decades ago by discovering several unique features of the Pt NMR of oxide-supported small platinum particles [5]. Specifically, they found that the overall Pt NMR lineshape for supported catalysts is extremely broad, of the order of... [Pg.477]
