Well dispersed CuO nanoflakes were successfully achieved via a fast and self-heating route. The physical properties of the as-prepared products were analyzed by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), nitrogen adsorption-desorption measurements, transmission electron microscopy (TEM) and selected area electron diffraction (SAED). Meanwhile, the catalytic activity and the catalytic advantage of CuO nanostructures are discussed with the help of first-order kinetics investigation for methylene blue degradation. It is found that self-heating in the reac...
