摘要
CuO nanoflakes and ball-like CuO self-assembly from nanoflakes have been prepared hydrothermally at 150℃ for 10 h and 15h respectively,by using methenamine as precipitator.The phases and morphologies of the as-prepared products were characterized by X-ray powder diffraction(XRD),scanning electron microscopy(SEM),and transmission electron microscope(TEM).Possible formation mechanisms for ball-like CuO nanostructure self-assembly from nanoflakes were briefly proposed.The catalysis of CuO nanostructures with different morphologies for ammonium perchlorate(AP)decomposition was investigated by thermal analysis.

The phases and morphologies of the as-prepared products were characterized by X-ray powder diffraction （ XRD）, scanning electron microscopy （ SEM ）, and transmission electron microscope （TEM）. Possible formation mechanisms for ball-like CuO nanostructure self-assembly from nanoflakes were briefly proposed. The catalysis of CuO nanostructures with different morphologies for ammonium perchlorate （AP）decomposition was investigated by thermal analysis.
