Abstract
In this paper, foam nickel supported catalysts copper-manganese oxides are investigated with respect to ozone decomposition. Firstly, The manganese and copper-manganese oxides are prepared by the coprecipate method. XRD, SEM are employed to explore the structure and morphology. Secondly, foam nickel supported catalysts center are assembly by the Polyacrylic acid as the binder. FT-IR is used to detect the bonding strength. Thirdly, the catalytical property of powder and foam nickel framework is investigated in detail. The results indicated that the Mn3O4 powder with 50W% CuO has the high catalytic activity of 92%, and when being supported by foam nickel, the samples possess high decomposition activity, up o 90%. The prepared catalysts as a perspective industrial material and technological process for ozone decomposition could be developed in the interior air clean field.
