Study On The Synthesis And Photocatalysis Of TiO₂ Coating Compound

In this paper, chemical and electrochemical plating composite compound deposition in the stainless steel surface preparation Ni-P-TiO₂ photocatalytic film, an initial deposition on the surface of stainless steel TiO₂ principle, the process of preparation and photocatalytic degradation of methyl orange efficiency factor. And composite deposition in the Ni-P-TiO₂ composite membrane doped cerium ions to increase the composite film photocatalytic properties were studied. The main conclusions are as follows:1. The use of chemical plating method composites, in the stainless steel surface has been prepared by uniform Ni-P-TiO₂ composite films by orthogonal experimental design, analysis of the complex factors in the process of plating film on the photocatalytic degradation of methyl orange efficiency, to be Preparation of the best conditions.2. In order for the stainless steel cathode, anode as graphite film, using direct current deposition, the surface of stainless steel in electro-deposition Ni-P-TiO₂ composite film. Through orthogonal experimental design, select the appropriate current density and deposition time, we got the Ni-P-TiO₂ composite film in natural light on the degradation of methyl orange efficiency of up to 46.1 percent.3. Trying to fish for the parameters of the best prepared on the basis of the chemical composite plating methods used in the preparation of the surface of stainless steel cerium ions of rare-earth-doped Ni-P-TiO₂ composite film, in the same experimental conditions, the use of the methyl orange light catalytic degradation of the experiment. Research shows that the amount of cerium ions doping on the Ni-P-TiO₂ composite thin film photocatalytic activity has improved significantly.
