The reaction mechanism of CO oxidation catalyzed by several Pt3M (M=Pt, Ni, Mo, Ru, Pd, Rh) clusters has been investigated with density functional theory calculations in the present work. The reaction prefers to proceed via Langmuir–Hinshelwood mechanism. The calculated barriers for the reactions mediated by bimetallic clusters are comparable with that catalyzed by monometallic Pt4 cluster. According...
Kinetic studies of vinyl acetate (VA) synthesis were carried out for Pd (1.0 wt%)/SiO 2 and Pd (1.0 wt%)–Au (0.5 wt%)/SiO 2 catalysts, with highly dispersed metal particles (Pd and Pd–Au) characterized by X-ray diffraction and transmission electron microscopy–energy dispersive spectroscopy (TEM-EDS). The kinetics of the related CO oxidation reaction were also explored. The kinetics...
