The Nano-copper Oxide, Preparation And Characterization Of Cuprous Oxide

CuO nanoparticles have been prepared using Cu(OAc)2 as the starting material and several monobasic alcohols as the solvent. The influence of the variety of alcohol, the reaction conditions and the addition of water on the microstructure of products was investigated. The as-prepared CuO nanocrystals were characterized by XRD, TEM, FTIR and UV-Visible absorption spectroscopy. The results indicated that the spherical CuO nanoparticles with an average size of about 5 nm could be prepared at higher temperature. The well-dispersed needle-shaped CuO nanocrystals could be obtained by adding small amounts of water into alcohol solution of Cu(OAc)2. The time and amount of adding water, the addition of crystal seeds and NaOH have great influence on the microstructure of CuO nanocrystals. The reaction mechanism was discussed on the basis of experiment results.The Cu2O nanocrystals of different morphologies were prepared using hydrazine hydrate as the reducing agent. The catalysis of as-prepared CuO and Cu2O nanocrystals on ammonium perchlorate decomposition was investigated by thermal analysis. The results indicated the catalytic activity of as-prepared CuO and Cu2O nanocrystals on ammonium perchlorate decomposition was high.
