摘要：

A new solvothermal technique for synthesizing nanostructured microspheres of nickel oxide (NiO), zinc oxide (ZnO) and tricobalt tetraoxide (Co(3)O(4)) using nitrate precursors, urea and sodium dodecyl sulfate as a surfactant is described. The microspheres were shown to exhibit a morphology resembling a collection of platelets with nanoscale thickness. The surface area of the microspheres ranges from 62.8(+/- 0.3) to 192.9 (+/- 1.3) m(2)/g, which appears to correspond to the density of platelet packing in the microsphere. The interior structure of the microspheres was investigated with a dual beam focused ion beam-scanning electron microscope and shown not to develop a hollow center. (c) 2007 Elsevier B.V.
