Research On Synthesis, Modification And Its Composites Of Copper Oxide Nanorod

Copper monoxide nanorods with one-dimensional structure were used as a kind of important inorganic nanomaterials in magnetic materials, light absorption, chemical activity, thermal resistance and catalyst in a wide range of applications. At present more and more CuO nanometer sphere were synthesized. But most of them reunited seriously. However, the study of the one-dimensional nano CuO with special morphology is still very rare and not very good. Certainly, the reaction mechanism is also not quite reasonable. This paper combines the hydrothermal and precipitation calcining method, through adopting urea as mineralization agent. Then the nanometer CuO precursor was gotten in hydrothermal reaction. The uniform one-dimensional nanometer CuO with porous structure then be investigated its catalytic and antibacterial properties; On the basis of traditional modification, we use the polymer coating modification to form the special CuO composite particle. To expand their application, several nanometer function CuO composite materials were synthesized.The study includes the following five parts:(1) Copper monoxide porous nanorods of 100-200 nm in diameter and 2-3μm in length were successfully synthesized using a hydrothermal reaction method in the presence of urea. The results of catalytic activity indicate that CuO nanocrystal promoted potassium chlorate and peroxide decomposition. When the ratio of H2O2 to CuO is 5 to 1, the decomposition of peroxide is perfect.(2) KH-570 silane coupling agent was used to modify the prepared copper oxide nano-rods for an organic surface. Certainly, the CuO/PMMA and CuO/PS composite particles were synthesized via the polymer coating on the surface of nano-copper oxide. The thermal stability and the dispersion of composite particles were investigated in this paper.(3) PANI-CuO nanocomposites were prepared by in-situ polymerization. Then the products were characterized by some analysis techniques. The results indicate that PANI-CuO nanocomposites were core-shell pattern including nanorods and nanosphere. The amount of PANI in the nanocomposites is estimated by TGA results. The antibacterial action of PANI/CuO nanocomposites increased with the increasing ratio CuO nanorods.(4) Copper nitrate as copper source, attapulgite as a carrier, urea was served as mineralizing agent, the precursor of copper oxide/attapulgite composite was prepared by hydro-thermal reaction. Then the sample was gotten by calcining the precursor. The research shows that copper oxide/attapulgite composite has a high catalytic activity to catalyze methylene blue wastewater, a perfect antibacterial action to Staphylococcus aureus and Escherichia coli.(5) Using potassium ferricyanide as an oxidant, thorn-like microspheres of polyaniline with better soluble and comparatively large BET was prepared via chemical oxidation. The influence of different types of oxidant, the molar ratio of oxidant on morphology and electrical properties of product were investigated in details.
