Abstract
We report on ultra-high catalytic activity of metallic structures consisting of densely packed assemblies of nano-size metallic (Cu) granules. These nanostructures are fabricated by a new method of laser electrodispersion. The major results on experimental studies of catalytic activity of Cu nanostructures are presented by the example of dichlorobutene isomerization. The observed high catalytic activity of granulated Cu nanostructure is explained by the presence of charges appeared at the granules due to thermally activated inter-granule electron tunneling. The charge state of the structure is analyzed by using newly developed Monte-Carlo model.
