Bimetallic Gold-Palladium Supported on 5A Zeolite and Their Catalytic Activity for Vinyl Acetate Synthesis Xianzhong Mo1,a, Hualin Hu1,b, Dengfeng Tan1,c, Ting Guo1,d 1College of Chemistry and Life Sciences, GuangXi Teachers Education University, Nanning, 530001,China aemail: moxianzhong@gxtc.edu.cn, bemail: dewxfss0307@163.com, cemail: tdflxe1314@163.com, demail: yingyonghuaxue08@163.com Keywords: 5A Zeolite; Gold; Palladium; Catalytic Activity Abstract. 5A zeolite supported Gold-Palladium (Au-Pd) bimetallic were prepared and used in vapor phase oxidation of ethylene to synthetize vinyl acetate (VA).
The structure of Au-Pd/5A zeolite catalyst was characterized by a scanning electron microscopy (SEM) and X-ray diffraction (XRD).
The common carrier have silica, alumina, 5A zeolite and so on ,among 5A zeolite as the most special carrier in catalyst attracted extensive attention due to its abundant pore structure, high dispersion and stability.
It is the aim of this study to prepare Au-Pd/5A zeolite catalyst by using Au-Pd bimetallic as active components and 5A zeolite as carrier and to describe the structure of Au-Pd/5A zeolite catalyst by AAS, SEM and XRD; in addition, The catalytic activity of the Au-Pd/5A zeolite catalyst under laboratory conditions were also determined in vinyl acetate synthesis by a kind of the fixed bed reaction device.

YAG is widely applied as the structure materials and the functional materials because of some excellent performances in the chemistry.
Introduction Yttrium aluminium garnet (YAG or Al5Y3O12) adopts the cubic garnet structure, it is of great interest as a high-temperature engineering materials, due to its high-temperature strength coupled with low creep rates.
So Y3Al5O12 is widely applied as the structure materials and the functional materials because of stable chemical performance [3-4].
Be compare with single crystal, the mass manufacture of YAG polycrystal powder materials is easily realized [5], the performance of polycrystal materials is better than that of single crystal materials under the some specifically conditions, so it substitute for the single crystal materials to produce the structure materials and the functional materials [6-7].
The mainly superfine YAG particles show near-spherical, because YAG is cubic crystal structure [12].The partly sintering behavior among the particles is produced (Fig.4-b), because superfine YAG particles own the high surface energy, which show the high activation energy, the particles is easily sintered under the lower heat treating temperature, which indicate the sort of superfine YAG powder materials is easily prepared the mass materials under the lower sintering temperature, and help for the sintering behavior of other materials as sintering aid.

The XRD patterns show the formation of a single- phase orthorhombic perovskite structure with no peaks attributable to impurities detected.
The symmetry of the crystal structure will be different according to different tervalent rare earth ion doped into BaCeO3.
It can be calculated that the value of t of pure BaCeO3 is 0.86, and this value testify pure BaCeO3 has distorted orthorhombic perovskite-structure but not ideal cubic perovskite-structure [9].

Introduction The pavement as an essential engineering structure for the socio-economy development of a country, highlights the necessity of studies that seek the feasibility of using new materials and technologies that enable the reduction of transport costs.
Resilient modulus In general, the pavements are engineering structures that are, to most of his life, dynamic requests, unlike other engineering works that are required for static loads.

The structure of the salt was classified into brucite-like materials related to the so-called layered double hydroxides.
Salicylic acid has a big structure accompanied by reductor property due to the presence of hydroxide groups.
Hence, the utilization of this acid has a good consideration based on the green chemistry aspect.

The crystal structures of pure TiO2 and all TiO2-rGO catalyst samples were investigated via a X-ray diffractometer (XRD) (XRD-6100, Shimadzu, Japan).
This result indicted that the electronic conjugations inside the rGO structure were restored after the chemical reduction of GO [5].
The crystal structures of pristine TiO2 and all the obtained TiO2-rGO nanocomposite samples were illustrated in Fig. 2(a).
This result due to the amorphous structure and very low content of rGO compared with TiO2 [6].
