Optical catalyst of titanium Nano-Tube preparation and study on the oxidation of cyclohexane
Abstract: In today's world of advancing technology and science and technology progress and the level of continuous improvement of human living standards, for example, in developing countries, the crisis makes people feel more and more environmental pollution Environmental pollution has become increasingly difficult for each country to solve the problem Photocatalytic materials as a green material of photocatalytic degradation of materials, has become one of the most popular fields of catalytic materials science research Nano-TiO2 photocatalytic materials more prominent as the representative of the material, its high antioxidant activity, good chemical stability, which is the largest in its features and benefits Its absolutely have reason become green catalyst is the most promising development, low cost, nontoxic substances, does not pollute the environment in nature, there is a wide range of applications This paper uses four butyl titanate hydrothermal preparation of TiO2 into law The easy preparation of clear, synthesis of TiO2 nanotubes by surface area size of depends on the reaction conditions, catalytic efficiency of TiO2 nanotubes doped with photocatalytic activity is significantly improved Photocatalytic experiments, in cyclohexane solution at low concentration by adding photocatalytic degradation of TiO2 nanotubes, and then use the standard curve analysis of the degradation product of; use of photocatalytic activity of TiO2 nanotubes and temperature, catalyst characterization study
Key words:TiO2 nanotubes;Photocatalytic Degradation;Cyclohexane;Hydrothermal Synthesis
