Catalysts supported on γ-Al2O3 were prepared from [Re2Pt(CO)12], and from Pt (NH3)4(NO3)2 and NH4ReO4. The former samples were characterized by infrared and X-ray photoelectron spectroscopies (XPS) and by temperature-programmed reduction (TPR); the

It is well established that the surface composition of a metal alloy may differ markedly from that of the bulk. Theoretical treatments of this phenomenon have been mostly based on models for regular or related solutions. Experimentalists have reporte

Model Pt/γ-Al 2 O 3 catalysts were prepared and characterized in our laboratories. They were sintered in flowing oxygen at 600 °C for up to 24 h. Particle sizes, shapes, and relative positions were determined from bright field images, and crystal s

The benefit of Re in PtRe: Al 2 O 3 naphtha-reforming catalysts is clear, but its disposition and function are not. We report here results of surface analysis of ion-scattering spectroscopy and microanalysis by energy-dispersive X-ray spectroscopy
