Abstract: This paper reviews the recent experimental and theoretical advances in the surface structure and reaction of Pd-based catalysts, the role of Au and the reaction mechanism for Vinyl Acetate (VAc) Synthesis, which focuses on the study regarding Pd-Au catalyst. The common conclusion and existing problems through different research methods is analyzed and compared. Experiment methods, such as in-suit reaction and characterization technique, on Pd-based single crystal models combined with the theoretical calculation, such as molecular simulation on model catalysts, give a clear understanding of the structure-activity relationship, thus the limitations to synthesize microstructure-controllable catalysts can be overcome, which will also be the main focus of future research in this area.
