inactive to the adsorption and dissociation of hydrogen molecule). This phenomenon is called hydrogen spillover effect [ 2 ].
It was reported that hydrogen spillover happened in some metal supportedcatalyst, such as Ni, Ru, Rh, Pd, Pt and so on

are much more active in the CO oxidation than the Au/inert oxides systems. These facts suggest that reducibility of the support may be another factor influencing catalytic behavior of the Au/oxide supportcatalysts. It can be supposed that oxides of
monolith Ti mesh supportedcatalyst offers the possibility of application in continuously operated reactor, but this needs further research.

In the area of metal supportedcatalyst preparation, the most widely used methods currently are impregnation [ 11 – 13 ], the colloidal [ 14 ] and the polyol process [ 13 , 15 ]. Lu et al. compared

In recent years, metal nanoparticle supportedcatalysts have attracted much attention in fundamental research and applications owing to their unique size-dependent properties. However, metal nanoparticles are
