| 總結: | Title screen There described a novel environmentally friendly synthesis route of micro/nanostructured hollow spheres of AlOOH by oxidation of Al nanopowder in pure water under mild processing conditions. The reaction kinetics of the aluminum nanopowder interaction with water was studied using the method of continuous recording of suspension pH and temperature. There observed the change in Al{3+} concentration in the reaction medium and the rate of hydrogen release as well as TEM investigations of the intermediate reaction products at different stages of the process were performed. It is shown that AlOOH hollow spheres are formed through the aluminum core dissolution, Al{3+} ion diffusion through the surface oxide film and AlOOH nanosheets formation on the surface of the precursor oxide film.
